The Black Keys' rise from humble Akron, Ohio, garage duo to Grammy-grabbing, arena-rocking, platinum rock stars has been a gradual one -- with no shortage of headline-worthy moments. In other words, it's perfect fodder for the big screen. While there are no known plans to bring the Black Keys' story to Hollywood, it would definitely make a great movie. It would also make casting agents crazy, as no actors stand out as obvious choices to play singer-guitarist Dan Auerbach and drummer Patrick Carney. That said, we've done our best to pick actors for these roles -- read our picks below.

Dan Auerbach Played By Viggo Mortensen

With his fierce blue eyes, sharp nose and trimmed beard, Dan Auerbach cuts a striking and unique figure onstage. Casting someone to play the singer wasn't easy, but eventually, we settled on Viggo Mortensen, an actor with somewhat similar physical features and a resume that, in terms of eclecticism, mirrors the Keys' output. Mortensen has done indies (David Cronenberg's 'Eastern Promises'), blockbusters ('The Lord of the Rings' trilogy, 'G.I. Jane') and the occasional edgy role (he recently played William S. Burrough's in the big screen adaptation of 'On the Road'). Perhaps just as notable is his musical background; once married to Exene Cervenka of punk legends X, Mortensen has an extensive discography of solo albums, including collaborations with Buckethead. If nothing else, Mortensen could handle his own concert performance scenes.

Patrick Carney Played By Johnny Knoxville

It's not music, but juvenile mayhem that comes to mind when you bring up actor Johnny Knoxville of 'Jack Ass' fame. It takes more than a pair of thick-rimmed hipster glasses to play Patrick Carney -- but having them certainly doesn't hurt, and Johnny has taken to wearing them in the last few years, so that's one less worry for the prop man. Beyond that, his resemblance to the hard-hitting drummer isn't mind-blowing, but to be honest, we had a hard time coming up with actors who do look like Carney. But we would like to point out both the Black Keys and Knoxville are big fans out outlaw country music, and the actor even has his own label, Johnny Knoxville Records. That's gotta mean something, right?
