NEW YORK, Oct. 23 (UPI) -- Avengers and The Hurt Locker alum Jeremy Renner says Mayor of Kingstown may be a drama about addiction, corruption, incarceration and murder, but that doesn't mean the cast and crew don't have fun making it.

"Nobody smiles on the show, right?" Renner, 54, said during a cast panel discussion in New York Tuesday night.

"It's not like it's the greatest sort of place to come hang out. It's a prison. But we still do have a good time. We still enjoy each other's company and it really is a really nice set to be on," said the star, who is also a producer on the series.

"I think everybody feels really grateful for the job and everybody's creative with what they do. We have a really great cast and really amazing crew. It's a well-oiled machine, too. We move fast and we don't mess around. It's a good time, man."

Broadway icon and Season 4 newcomer Laura Benanti confirmed this is true.
