"On the whole people don't tend to recognize me from it because I look so different I guess," he admitted at the premiere of Tron: Legacy. "I think it's usually people's mums and dads that go 'see that guy over there, he's Aro' because they've seen me in stuff."
In Tron Legacy, Sheen adopts a very different look! Loosely inspired by David Bowie's look in the 70's, Micheal Sheen donned an elaborate sucked-in space suit to play Castor. "The costume was very uncomfortable but the look, this was one of my favorite looks I've ever had," he confessed. "It's just so extreme. It's like part 70s glam rock, part circus ring master, part Bridget Neilson. It's a good look!"
