If you're currently watching AMC's freshman crime drama "The Killing," then you know that co-star Joel Kinnaman is the most badass thing to happen to television since Jack Bauer electrocuted a terrorist using the inside of a lamp. As Detective Holder, Kinnman flaunts his Timothy Olyphant-esque looks while busting the baddest guys in Seattle, rarely playing by the rules.

Now, he's ready to show his sweeter side.

Kinnaman has been tapped to star alongside Greta Gerwig ("Arthur") in a new romantic comedy titled "Lola Versus."

The movie follows a string of major roles for the actor, with "The Killing" being picked up for a second season as well as parts in the upcoming action movie "The Darkest Hour" and David Fincher's "The Girl with the Dragon Tattoo."

"Lola Versus" focuses on Gerwig's character, who, according to Hollywood Reporter, finds herself broken up with only a few weeks before her wedding and forced to once again face singledom. Kinnaman plays the tattoo artist fiancee that breaks her heart, while "The New Adventures of Old Christine" and "The Future" actor Hamish Linklater plays the new guy crushing on her.

Stomping around in rom-com territory may seem like an odd choice for Kinnaman, but he has a particular sense of humor that shines on "The Killing" that may be perfect for the off-kilter indie attitude of the film. Backer Fox Searchlight has a history with straying for the norm with their comedies -- think "Juno" and the upcoming "The Art of Getting By" -- and Kinnaman's casting makes "Lola Versus" one to keep on the radar.
