Will Smith introduces the 46664 concert in honour of Nelson Mandela in Hyde Park, London June 27, 2008.

Will said: "It's hard to beat that dude. He has another gear. He did two-and-a-half hours in France for 'Mission: Impossible' on the red carpet. Now when I go to France, people will say, 'You know, Tom was out here for over two-and-a-half hours.' "

The 39-year-old actor also revealed playing boxing legend Mohammad Ali in 2001 hit 'Ali' inspired him to have more confidence in himself.

Actor Tom Cruise introduces actor Adam Sandler as the recipient of the Generation Award at the 2008 MTV Movie Awards in Los Angeles June 1, 2008.

Will - whose performance earned him an Oscar nomination - explained: "When I was doing 'Ali', I realised that he kept saying, 'I'm the greatest, I'm pretty,' to make himself believe it. He doesn't believe it, but he was dealing with racism.

He was reacting to pain and rejection. He said it so much that he started to really believe it. That is what I've tried to do for myself."
