Jodie Foster: Mel Gibson was right actor for the role
The film, which was Foster's directorial debut, tells of a troubled man who decides to use a beaver hand-puppet as his sole means of communicating.
Speaking at Cannes earlier this week, Foster defended the casting choice after being asked if Gibson's troubled personal life would impact on how audiences respond to the character.
She revealed that the Braveheart actor was first on her list when it came to choosing someone to take on the role.
"He's somebody that really understands how to handle humour and the lightness and the charm of the character, but also has a deep understanding of the struggles and … he would keep his feet firmly placed in the drama," she added.
The film, which also stars Anton Yelchin, will be released in the UK on June 17th.
