Kat Dennings (Nick and Norah's Infinite Playlist) is in talks to join Woody Harrelson and Sandra Oh in Defendor, according to The Hollywood Reporter.

Peter Stebbings wrote the script for the film with which he will also make his directorial debut. Defendor centers on a regular guy (Harrelson) who believes he has a secret superhero identity. Dennings will play a teenager he befriends, while Oh is cast as his psychiatrist.

Principal photography begins next month in Toronto.
