Listen to Jason Aldean on iHeartRadio

(WENN) - Jason Aldean turned down a big role in upcoming Western Sweetwater in favor of a smaller part, in case he turned out to be an awful actor.

The singer, who makes his movie debut in Sweetwater, was initially asked to play a major character, but he feared his acting skills would look amateur next to his experienced co-stars Ed Harris and Mad Men's January Jones.

In a radio interview he says, "With it being my first time acting, I basically turned (a bigger) role down and was like, 'You got something that's a little bit less of a part?' I just kind of wanted to try a smaller part and see if it was something I was even interested in.

"If I was gonna be bad, I wanted to be in the film (the) least amount of time as possible."

Sweetwater is set to premiere at the Sundance Film Festival in Utah later this month.
