When I marvel at the jaw-dropping accomplishments of Joe and Anthony Russoâs Avengers: Endgame (and I do it often, because I still canât really believe that this movie exists), I tend to point to one specific scene that melts my brain at the sheer number of things that occur in it. It happens when Captain America (Chris Evans) throws Mjolnir through the air so that Spider-Man (Tom Holland), while holding onto the Infinity Gauntlet, can soar long enough for Valkyrie (Tessa Thompson) to catch him on her flying horse and whisk him to safety. How does that exist on screen?!
