Colin Farrell has reunited with director Yorgos Lanthimos for "The Killing of a Sacred Deer," which premiered this week in Cannes. While Lanthimos insists that the film is a comedy, Farrell told Reuters, "There are some funny things in it, some situational kind of leanings that are funny in their awkwardness, I?m sure. But ... for me anyway, it's a black tragedy." Farrell plays a character who is struggling with a traumatic event from his past. Farrell also stared in Lanthimos's "The Lobster" which competed at Cannes two years ago.
