"Men in Trees" star James Tupper will portray actor Joseph Cotten in Richard Linklater's indie biopic "Me and Orson Welles" says The Hollywood Reporter.

The film follows a teen (Zac Efron) who is cast in Welles' 1937 Broadway staging of "Julius Caesar" opposite Cotten.

Cotten's career was launched with roles in Welles' classic "Citizen Kane" and "The Magnificent Ambersons" before going on to several Alfred Hitchcock films and Welles' 1949 thriller "The Third Man".

Holly Gent Palmo and Vincent Palmo Jr. adapted the screenplay from Robert Kaplow's 2003 novel, whilst Claire Danes also star.

Principal photography has begun in the Isle of Man, London and New York.
