I know of about 3 of these people... I really liked Corin Nemec on SG-1, HATED Tom Cruise for War of the Worlds (the last decent thing he did was Minority report), and have only seen Will Smith in Men in Black, but I liked him there.
Looking at that list, I think I need to expand my movie genre tastes beyond ‘science fiction’... maybe include ‘fantasy’ or ‘action’ as well?
Or TV or music?
