The 44-year-old What Happens in Vegas actor shared details about how he changed his facial hair for his latest film Vengeance during an interview on Jimmy Kimmel Live Thursday with special guest presenter David Alan Grier.

The movie Quentin Sellers, a small-town Texas music producer, is played by Kutcher, and he sports a pencil-thin mustache. Kutcher recalled thinking of such “bad guys” with thin mustaches as Smokey and the Bandit and Cannonball Run when he first saw the role, saying:

“It’s interesting. He kind of had that Boss Hog sense about him.” “Okay, I guess this individual has that aura of sophistication,” I thought.

Kutcher said of Kunis, 38, “Then my wife had to deal with that and everything was fine.”

Grier, 66, asked Kutcher how she felt about her facial hair. Kutcher replied that Kunis was very understanding. Since we’ve been dating for seven years, she exclaimed, “Oh, that’s like a different person!” when I brought the mustache home. Kucher said.

Regarding the film itself, BJ Novak makes his debut as a star and director with Vengeance. BJ approached me with an amazing script he had written and said, “Hey, I’m going to direct this thing, it’s supposed to be my directorial debut, and there’s a role I want you to cheeks,” according to Kutcher.

Kutcher was impressed after seeing the script and decided to work on the film.

Along with Vengeance, Kutcher’s highly anticipated That ’70s Show spin-off series That ’90s Show will soon premiere on Netflix.

Along with Kunis, Topher Grace, Laura Prepon, Wilmer Valderrama, Danny Masterson, Debra Jo Rupp, Kurtwood Smith, Tanya Roberts, Don Stark, Lisa Robin Kelly and Tommy Chong, the actor appeared on That ’70s Show from 1998 to 2006. Before agreeing to reprise their roles, Kutcher and Kunis had a chat, the actor revealed on a previous Vengeance red carpet
