Tom Hiddleston Uses His Loki Powers To Undergo A Magical Transformation On The Set Of Crimson Peak!

We are LOVING Tom Hiddleston 's period look for the upcoming horror film Crimson Peak!

So inneresting seeing our boy in and out of costume!

Tom is looking dark and brooding in his all-black street ensemble, then seems to come alive with mischievous glee in his sexy ebon cloak!

And though we're sure it wasn't really a supernatural costume change, there was magic involved - after all, he was nearly naked for a moment! LOLz!

Ch-ch-check out the pics (below) to see Tom, Charlie Hunnam, and more get in and out of character!
