Robert Hayes
The actor Robert Hayes played Bo in American Reunion. Hayes did not appear in the first three American Pie films, American Pie, American Pie 2, and American Wedding. He only appeared in the fourth American Pie film.
Hayes loved working on the set of the American Reunion, saying, “With American Pie being the top comedic franchise in history, the cast and crew constantly cracked jokes in between takes, pulled pranks on each other, and laughed our brains out after we filmed most of the scenes because they were just so funny. Seann William Scott brought a certain type of energy to the set that I feel nobody had the capability of bringing.”
