Brr. There is a fine, yet crucial difference between two close descriptors. Calling someone 'cool' is a Hollywood honour which traditionally goes to classically unflappable actors like Samuel L Jackson, Sean Connery, and maverick, stylistic directors like Quentin Tarantino and Steven Soderbergh.

On the other hand, calling them 'cold' is a whole different ball of un-warm wax, as Michael Moore and 50 other celebs realised with Film Threat online magazine's Frigid 50: The Coldest People in Hollywood 2004 list.

Moore, the overblown director of Fahrenheit 9/11, holds a quite unenvied top position, and the magazine's editors say he was singled out for his ego.

Other stars on the mercurially intemperate list include Halle Berry, Paris Hilton, Jimmy Fallon, Ben Affleck, and Disney head Michael Eisner.
