The movie was shot last year in Michigan and marks the former "Friends" star's second time directing a feature film.
The film's publicist Cid Swank says Toronto's the "perfect festival for everyone to see the finished movie for the first time."
It's about the fallout from an attack by an online sexual predator and stars Clive Owen, Catherine Keener and Viola Davis.
The film is set in the Chicago suburbs but was largely filmed in Michigan.
