James Norton was photobombed by his co-star Thomasin McKenzie at the premiere of their film Joy. The two actors were attending the BFI London Film Festival when Thomasin playfully jumped into the background of James' red carpet photos. The film Joy tells the true story of the development of in vitro fertilisation (IVF) in the 1960s and 1970s. It follows three British scientists who worked against the odds to make IVF possible. The film stars James Norton as Robert Edwards, Thomasin McKenzie as Jean Purdy, and Bill Nighy as Patrick Steptoe.
