Cory Monteith's 'All The Wrong Reasons' Trailer Revealed (VIDEO)

WATCH: Cory Monteith In Last Film Role

One of 'Glee' star Cory Monteith's final two films has unwrapped its trailer.

'All The Wrong Reasons' sees Monteith, who died on 13 July in a Vancouver hotel room, play a store manager.

The film will have its debut at the 2013 Toronto International Film Festival, which begins this week, and focuses on the lives of four people following a traumatic event.

"Cory saw the film a few weeks [before his death]," director Gia Milani said in an statement to EW.com. "He said he loved how layered it was and he thought it was intense. He loved Finn [his character on 'Glee'] and always talked about how blessed he felt to have been cast in 'Glee,' but like any artist, he wanted to play other roles too. I think he wanted to prove to himself he could do more. And he did prove it. When I last saw him at the screening, he looked super fit, had a lot of energy. I think that’s why this is such a tremendous shock. He seemed to be doing so well."
