Cory Monteith will be seen on the big screen one last time at theToronto International Film Festivalin September.

In the upcoming crime drama, "McCanick," Monteith portrays a drug-addicted criminal sent to prison for murder in one of his last two film roles. The part was close to Monteith, who had struggled with addiction on and for years.

The movie's director, Josh C. Waller, told the Los Angeles Times that Monteith wanted to dive into his own past experiences as he immersed himself in the role: "He was very vocal about his past, and said he wanted to tap into things from his youth that he hadn't been able to use as an actor yet. He didn't say it was a cathartic experience, but you could sense it."

Another one of Monteith's final films, the comedic-drama "All the Wrong Reasons," will also premiere at the Toronto Film Festival.

The Canadian native died July 13from a toxic mix of heroin and alcohol. His Finn Hudson character will be written off in an upcoming tribute episode of "Glee," set to air in October.
