The full name of Bill from Bill and Ted fame. Bill is the best friend of Ted "Theodore" Logan in the movie Bill and Ted's Excellent Adventure and it's sequel Bill and Ted's Bogus Journey. With Ted, he forms the band Wyld Stallyns. Before getting a phone booth/time machine, Bill was often found at the Waterloo water slide park and the Circle K. Now his music is creating a utopian society.
Everyone knows Keanu Reeves played Ted, but who played Bill? Why it was Alex Winter, who later went on to write/direct/star in the freakshow flick "Freaked". More recently, he wrote and directed a film called Fever, which I hear is actually pretty good. Won't you be the hit of the party?
