'Rescue Me's' Denis Leary Spills Series Finale Secrets (Video)

It all comes to an end Wednesday night for Tommy Gavin and his fellow firefighters.

FX's Rescue Me airs its last episode at 10 p.m., timed to the 10th anniversary of the 9/11 terrorist attacks.

While star/co-creator Denis Leary is keeping the ending of the show close to his vest, he did recently drop some hints about what fans can expect.

Among the tidbits Leary revealed is that "there's a pretty big fire towards the end."

In fact, the last scene was shot with "about 150 firefighters, down on the waterfront in New York," he said during the summer Television Critics Assn. press tour, as reported by Starpulse.com. "It was a very complicated shot. That was the last thing that we shot, actually. It was nice."  

He also hinted that a character dies in the final episode, which is titled "Ashes."

"Staying true to the nature of the show, it was important that somebody or somebodies were going to have to pay the price," he said. "Because we were dealing with grief, it was a great thing for all the characters on the show to have to deal with again. It’s also the nature of what these guys do for a living. It’s such a life and death job that that never went away from the show. We didn’t think it was the right way to go out without dealing with that again."

Meanwhile, Leary shot down the idea that there might be a Rescue Me feature film in the future.

"Not a chance ... because I think we wrapped it up, hopefully," he said. "If you watch the finale, there’s really no way you could have a movie."
