Michael Dowse will direct the film, which features a screenplay by Elan Mastai. Based on the play Toothpaste and Cigars, by T.J. Dawe and Michael Rinaldi, the film involves Radcliffe's character attempting to have a platonic relationship with Kazan's character -- with "friend" being the "F Word" referenced in the title.
Kazan's Broadway credits include A Behanding in Spokane, The Seagull, and Come Back Little Sheba. She is also the author of the play, We Live Here, presented by Manhattan Theatre Club last year.
Radcliffe has starred on Broadway in How to Succeed in Business Without Really Trying and Equus. He is best known for playing the title character in all of the Harry Potter films.
