When I think of the definition of cool and when I look at people John Travolta is really the definition of cool because not only is he great in all his movies but as a person he's just really cool.

You know you grow up with the image of John Travolta being super cool - 'Saturday Night Fever ' Brian De Palma handsome young god... he in reality is a very silly man. And I mean that in a good way. He'll walk around the set talking in little weird voices making people laugh.

I once sang 'Summer Nights ' from 'Grease ' at a bar in Melbourne with John Travolta who's a good friend of mine. He looked cool singing the part of Danny - sitting in an armchair smoking a cigar - while I got stuck playing Sandy.
