Stuart 'Stu' Macher is the second killer in Scream. He is represented as insensitive, eccentric and is a fan of horror movies. He is going out Tatum Riley and helps Sidney's boyfriend, Billy, in the killings apparently for no real reason, except for "peer pressure." They first attack Casey Becker when she dumps Stu for a quarterback named Steve. In the conclusion of the movie, it is revealed that Stu and Billy took turns at doing the killings while the other made the calls. Stu is killed when Sidney hits him with a vase, and drops a TV on his head.
