But I have just learned that Bruce Boudreau was used as an extra in Slap Shot. Yeah, the movie. Check out this 20-second clip of the Chiefs' game against the Hyannisport Presidents.
Number 7 on the Presidents is apparently a young Boudreau, who played at the time for the Johnstown Jets of the short-lived North American Hockey League. The film apparently tapped the Jets for extras pretty often, and - well - there he is.
