have a day to reflect on the competing claims of the two remaining candidates, emmanuel macron and marine le pen. voting is on sunday in an election which is being closely monitored across the european union and beyond. coming up in the next half hour, newswatch — but first, here's click. in the shadow of battersea power station in london, the future of mankind hangs in the balance. our two heroes are on a desperate mission to save the earth from being wiped out by an asteroid... hang on, you're bashing some boxes around now. what's this? ooh! 0h, 0k, well done! oh! ..and, quite frankly, they're being hopeless about it. do you want some nitrogen? can i throw it to you? 0k, i've got no feet! yes, throw it to me. all right, look, here we go. can i catch it? got it! 0k, well, whatam i actually doing with it now? um, i don't know — hang onto it, i suppose. well, is that why you've given it to me, because you don't know what to do with it? this is a vr escape room in space, where the objects you pick up and drop bounce around in zero g. it really shows how vr can create experiences that would be impossible to achieve in a real escape room. but it just looks like any landmass with some sea next to it! yeah, but there's a long wiggly bit! i don't recognise the curve. there's a long wiggly bit over here, right? yeah, although what's funny, of course, is that escape rooms started online, then they moved to the real world and now, they're now becoming this sort of next gen hybrid thing. true. not that it matters, as right now, i think we're running out of time! both: argh! lara chuckles 0h, we didn't manage to save the world. i'm s o rry! yeah, you've all gone the way of the dinosaurs, i'm afraid. apologies. we've known for some time now that video games can help alleviate stress and anxiety, and only last year, we looked at a device called the mdoloris, which is usually used by doctors to see whether patients who are sedated are feeling pain or not. yeah, but they've also been conducting other studies using the machine, specifically with kids who have cancer, to find out whether playing video games could do more for them than just be fun. omar mehtab has been finding out more. ah, nervous. i'm pumped, i'm excited! i'm a little bit nervous. we've arrived at the hospital la paz in madrid and we're here to meet the kids fighting cancer. hello! omar chuckles why's that? well, it's because i'm about to play some video games with them! this here is my new friend marco. how long have you been in the hospital? laughter ah, pokemon? yes. yeah? i have pokemon as well. i've got my pokemon — can i get my pokemon? can i show him? do you know how to play? go for it, man. check out my pokemon. now, we're notjust here playing games for the sake of it. rather, it's said to reduce the pain that these kids feel. a trial at this hospital has been studying these children, who often feel pain due to their condition and the adverse effects of chemotherapy. the mdoloris machine. it monitors a person's autonomic nervous system, which unconsciously regulates body processes such as breathing, blood pressure and heart rate so doctors can, at a glance, see the level of distress a patient may be in. the lower the number out of 100, the more they are in. it quantifies pain. we looked at this machine last year, where doctors said it helped assess how much pain someone was actually in, so they can administer the right amount of painkillers so as not to over— or under—dose them, and it was critical in treating covid patients as well. but now, they're using it to try and prove one of the most popular theories around. there have been various studies over the years looking into the relationship between gaming and pain, and by using this machine, they can objectively say when someone is feeling more or less pain. but why are video games having this effect? now, this trial has been peer—reviewed and published in thejournal of medical internal research. they had 20 kids in total playing video games for an average of 2.3 hours every day, and that was enough to bring about less pain and less need for morphine, showing how effective this non—medical, non—invasive hobby may be. 0k, me personally, i easily get vexed with video games if things don't go my way. but for these kids, not so much. the theory is that adolescent kids can gain more pleasure from video games than any other age range. i imagine he's in pain... another level! i imagine he's been in pain, but right now, that doesn't matter! because he's just fully absorbed and right now, all — this is all he cares about. daniel here, for instance, was one of the first trialists and immediately saw the benefits. and it all began when this psp was handed to a patient and they similarly noticed how affixed the kid was to it. now, they want to take their findings further. so, maybe one day, we'll find playstations, xboxes and nintendo switches become standard in hospitals. untilthen, maybe i'll also do a bit of gaming when i'm not feeling too great. so, over the last few weeks, we've been looking at some of the films nominated for best visual effects at this year's oscars, and this week, it is the turn ofjames bond! did you know that no time to die is the first bond movie that's been nominated in the best visual effects category in 43 years? moonraker was the last one in 1979. yes, of course. and here is some of the amazing work that went into the film. now, your enemy is my enemy. his name is safin. what does he want? revenge. me. - the bond films have a rich heritage of shooting all of their extraordinary action for real, and this film was absolutely no different. there was visual effects in it, but they were not up front and centre. so for instance, in the norway lake sequence, the production actually went to norway and they filmed on a real lake, a realfrozen lake in norway. but as with any production, when you shoot throughout the day, the footage looks different from shot to shot. there was kind of one or maybe two shots which everyone was happy with the lighting conditions. we had a task — to try and match the lighting across all of the shots, and in order to do that, we simulated a cg world where the lighting was exactly the same, and then we used a number of techniques to copy and mimic what we were seeing in the computer. so, rather than — we still used the photography and built on top of it rather than replacing it whole hog, but we used the simulation to tell us what that should look like. we had an amazing special effects team that really did — and a stunt team that really did jump land rovers through the air, and when we needed to replace things like that for lighting or forfilling in the background, we kept exactly that stunt. so, on a james bond film, no—one really wants to resort to c6! stunts and things like that, so they really do capture everything in camera. but when they, for sort of timing reasons, they take a chunk out of the middle of a chase, suddenly the continuity of where those vehicles are and where they need to be sort of goes out the window. that's when we do come in. we try and find a plate that maybe has got the toyota in it, which is bond's car, but it doesn't have the land rovers there, so had a motorbike. so we erased the motorbike but we'll put the land rovers in. and that's the kind of work that we are doing. it's not very flashy work to put in the grass that was completely chewed up by the stunt team and to replace that, but it does need to be — it does need to look really accurate. and the attention to detail that our environment team had to go to to model the tufts of the grass that matched the scottish highlands, where they were shooting — unless we go to those sort of lengths, you don't end up believing it and it all feels like a bit of a fudge, and we're not interested in fudging it in 2022. and i'm afraid that's it for the short cut of click for this week. the full—length version is of course waiting for you right now on iplayer. and as ever, you can keep up with the team on social media. find us on youtube, instagram, facebook and twitter, @bbcclick. thanks for watching. we'll see you soon. bye— bye. hello. welcome to newswatch with me, samira ahmed. the bbc�*s kyiv correspondents tell us about the challenges of reporting from the conflict zone. and is it accurate to describe marine le pen as the far—right candidate in the french election? the suggestion this week by keir starmer that borisjohnson criticised the bbc�*s coverage of ukraine, was angrily dismissed by the prime minister and later retracted by the labour leader. it's a sign that while politicians are quite happy to attack the bbc on other subjects, the corporation's coverage of ukraine is so widely respected that criticism of it is seen as beyond the pale. particular praise has been given to the team of reporters on the ground in ukraine. among them, kyiv correspondents. below ground in our bombshells shelter the adrenaline has run out, people are visibly tired, visibly upset from everything going on. and when you come up, it is this. empty. and you can feel the tension. moscow has urged people living here to leave as it lists new targets, but for so many people but is not an option. former professional rugby playerjames waterhouse only arrived for his first foreign posting in mid—january. little more than a month later he found himself covering his face war. in doing so with the approval of viewers. he finds himself impressed how james waterhouse is sharing his about the ability to explain what's going on on the ground in ukraine on the bbc different james waterhouse is currently in the uk and will be returning to kyiv and hejoins me now.
