An interview with Nick Frost in
The Guardian includes the following:
"Nick finds acting difficult because he doesn't have the back-up of training. On the Tintin film, the script kept changing, to such an extent that he and Simon were sometimes handed their words just minutes before they went on. "I need a week to really get a scene into my head. And you've got Steven Spielberg and Kathy Kennedy, who's the most powerful woman in Hollywood, and Peter Jackson, who's co-directing from New Zealand using iChat! It was the most stressful thing I've ever done. Having said that, Spielberg was amazing. Sometimes he'd run on at the end of a scene and do a little dance and punch the air."

"MTV meanwhile reported Tintin director Steven Spielberg used a specially designed video-conferencing system that allowed producer Peter Jackson to talk to him and watch everything on set while action sequences were shot in Los Angeles. Post-production work on the US$135m (NZ$234.9m) film
was about to start and would take 18 months, it reported."
