Jamie Dornan and Emily Blunt behave like no human beings you have ever met Credit: Alamy Dir: John Patrick Shanley. Starring: Jamie Dornan, Emily Blunt, Christopher Walken, Jon Hamm, Lydia McGuinness, Danielle Ryan. 12A cert, 104 mins For all those who groused that this year’s Oscar titles were too weighty and severe for their own good, here is the antidote: a film so frivolous and twee I felt as if my brain were leaking out of my nostrils as I watched. Expanded by John Patrick Shanley from his 2014 play Outside Mullingar, Wild Mountain Thyme is a romantic comedy about a man and a woman who were raised on neighbouring farms somewhere inside an advert for the Irish Tourist Board, in which the green in every field and hillside has been cranked up to a queasy hue.
