Simon Pegg revealed to the The Sunday Times that Steven Spielberg asked that he and Nick Frost play the Thompson Twins in Tintin.
“Steven’s smoking a stogy, cap on head, like he’s always been since I was a baby,” Pegg says, shaking his head in wonder. “I shook his hand and chatted about films. He gave me the mo-cap [motion-capture] camera, and I had a play around with it. Then he said, ‘Hey, maybe you and Nick Frost could play the Thompson Twins.’ In Tintin. A Spielberg movie. To work with him is beyond…” He trails off, lost for words.
I’m not sure how convincing they would be as twins, seeing as though they look and sound different. However, as the film will be in motion capture they could capture the essence of Frost and Pegg and turn them into twins for the big screen. It could work.
