"Bad Ass" movie star Danny Trejo has taken on his most surprising role yet ... as Marcia Brady. 

“Every time I get interviewed, people ask me what’s the hardest role I’ve ever played. Now it’s Marcia Brady,” Trejo told FOX411.

The actor plays a reimagined version of the iconic blonde teenager, wielding an axe and a leather vest in Snickers' new Super Bowl commercial. Trejo, 70, recounted how his agent broached the subject of said commercial.

“They called my agent. She said we might have a Super Bowl commercial for Snickers and you’ll be playing Marcia Brady and I said, ‘Huh?'”

Confusion aside, Trejo, a fan of the sweet treat, jumped at the chance partly because of his childhood crush on Mrs. Brady.

“I had a crush Florence Henderson when I was younger," Trejo said. "I would love to meet Marcia but I would prefer mom."

His real-life friend Steve Buscemi takes on the part of Jan Brady in the spot.

“I didn’t even know Steve Buscemi was in it until I get there," he said. "It was so hush-hush.”

As for whether Buscemi had any Jan-like jealousy over Trejo getting the spotlight as the favorite Brady sister, Trejo attributes his good fortune to one thing, and it wasn’t his axe.

“I have really nice hair. I think that’s why I got the part.”
