Mihaly “Michu” Meszaros (Hungarian: Mészáros Mihály; October 1, 1939 – June 12, 2016) was a Hungarian actor, circus performer/entertainer and stuntman, who as an American citizen was best remembered as a performer with Ringling Bros. and Barnum & Bailey Circus and for his role in the NBC sitcom ALF. He was 2 feet 9 inches (84 cm) tall. Throughout the 1970s and 1980s, Meszaros was a television and film actor, and he also appeared opposite pop singer Michael Jackson in a Pepsi commercial and on the Strange Days album cover for The Doors. His last appearance was in 2015’s Death to Cupid.
For the first season of the ALF television series, Meszaros donned a costume whenever a full-body shot was needed for scenes of the alien walking, running, or standing. For the most part, however, upper-body shots of a mechanical puppet were used instead, since the full-body costume was extremely hot and uncomfortable for the actor to wear for long periods of time under bright studio lights. The ALF puppet and costume can be distinguished on first view because the head proportions are slightly different.
