Watch: Tom Hiddleston Prepares For 'I Saw The Light' By Playing A Gig As Hank Williams

Only Lovers Left AliveFor someone who’s still to lead a big movie on his own, Tom Hiddleston is remarkably famous. The British actor has, of course, been in some huge films: he was the bad guy in the third-biggest movie of all time, "The Avengers," as well as two blockbusting "Thor" pictures. But outside the Marvel-verse, Hiddleston has mostly focused on smaller indies, like "Archipelago," "The Deep Blue Sea" and "Only Lovers Left Alive."

Hiddleston, who has time away from Loki for a while, may soon test his solo blockbuster mettle with "Ben Hur." But first up, the star is sticking to the indie world, playing the unlikely role of country superstar Hank Williams in a new biopic, and a first glimpse of how that might turn out has arrived.

The actor starts shooting the project, "I Saw The Light," soon, but MTV dug up a video of him making an impromptu appearance at the Wheatland Music Festival, playing a cover of Williams’ "Move It On Over." It’s a little difficult to see how he looks, but he’s surprisingly convincing vocal-wise. If there was any doubt that the RADA-trained Brit can pull off the smoky-voiced country singer, it’s certainly starting to dissipate. "I Saw The Light," which will be directed by "Flash Of Genius" helmer Marc Abraham, starts shooting in Louisiana next month, so could well be on the festival circuit this time next year.
