There is a brief interview with Michael Sheen on the BBC Newsbeat pages, where he mentions how tight security was on set.

“I remember someone whose job was containment and I thought: ‘What does that actually mean? Does that mean stopping people from getting on the set?’  And it wasn’t, it was to stop people on the set taking pictures and sending them out.”

He also talks about how he took the part to please his 10 year old daughter, Lily, so that she could go to the premiere.
