One of the best actors of all times. Best known for his main character role in Bonnie and Clyde, in which he starred opposite the great Faye Dunaway. Warren Beatty was handsome, clever, atractive and a great actor and yet he isn't that famous. One of the big injustices of life.
If you haven't seen any of his movies, I recommend you buy Bonnie and Clyde right away. Its well worth it.
Warren Beatty played Clyde Barrow in Bonnie and Clyde. Go watch that movie, or at least google Warren.
A situation in which a bet is placed and the better is a little unsure of whether they are correct, and the other party is certain they are correct. The bet is usually not money, but a humiliating punishment, or something not liked by the person who insighted the bet (i.e. dancing, eating seafood, wearing tights, etc.). The bet is often made by loved one's (i.e. girlfriends vs. boyfriend, wife vs. husband, etc.). Usually the male end of the bet is the wrong one and is forced to enact the punishment.
Jessica wanted to Warren Beatty Brandon that the character in the movie was not played by Warren Beatty but he didn't want to commit to the bet since he knew his punishment would be to go dancing.
