Many assume that for 2011’s superhero film Captain America, director Joe Johnston utilized technology which digitally placed actor Chris Evans’ face onto that of a smaller actor (famously pioneered by David Fincher and Brad Pitt in The Curious Case of Benjamin Button), however this is false. Johnston claims however that he did borrow a procedure from another famous film to complete the effect: John Woo’s Face/Off.

Johnston explains:

We surgically removed Chris Evans’ face and placed it onto the body of actor Jeremy Davies. Once those scenes were in the can [a filmic term, meaning “completed”] the surgery was reversed and both actors were put back to normal.

Jeremy Davies, perhaps best known for his mousy roles in tv’s LOST and 2002’s Maggie Gyllenhaal/James Spader rom-com Secretary joked that he wished that he didn’t have to change back. Evans grimly countered that he felt “very uncomfortable” around the more slender actor.
