Maybe he should reconsider being behind the camera? Ryan Gosling showed off his impressive muscles on the set of his directorial debut, How to Catch a Monster, on May 2. See more photos of Ryan Gosling. 

The handsome 32-year-old actor was spotted on the Detroit, Mich. set lifting a heavy box -- and looking hot while doing it. Dressed in a tight black T-shirt and black pants, Gosling's biceps were bulging as he carried the equipment around.

Though it appears Gosling has been bulking up, the Canadian actor won't be stepping in front of the lens for this project. Instead, he will be directing Mad Men star Christina Hendricks in the fantasy film about a single mother of two who is brought into a dark underworld when her teenage son finds a a road that leads to an underwater town.

"[Ryan] called me and asked me if I was interested in doing this film and I said: 'One, of course, yes, and two, why me? And three, I don't want to disappoint you,'" Hendricks (who costarred with the hunk in 2011's Drive) told the May issue of Flare magazine. "He's been fantastic, involving me artistically and letting me be along the road of casting and costume design. I've seen story boards and imagery and I've heard music. It's the largest role I've ever had, so this is one I"m definitely aware of my anxiety about."

The film is also set to star Gosling's real-life girlfriend Eva Mendes. The 39-year-old actress visited her boyfriend of almost two years on the set May 1.

In an interview with The Associated Press in March, Gosling said he was going to take a break from acting. "I've been doing it too much. I've lost perspective on what I'm doing," he said. "I think it's good for me to take a break and reassess why I'm doing it and how I'm doing it."

"There's a lot of pressure to be the lead of a film," he added. "I have done it. It's not my favorite way to work."
