Michael Kenworthy (born August 18, 1975) is an American actor who has been acting since the age of 5 He is most well known as the Commercial Kid, having done over 135 commercials and building a huge fan base in Canada as "Righty" of the Shreddies Gang whose 19 commercials aired for 20+ years due to revival of the classic spots in the early 2000s. Equally underreported he starred in 14 pilot sitcoms that never made it to broadcast along with innumerable guest appearances on other TV shows of the day that did air.

In addition he had a notable theatre career in independent films such as "The Giving Tree". Industry insiders remembered him for turning down two of the most successful sitcoms in TV history, the first being the Ben Seaver role in Growing Pains because his parents thought it would be too much of a commitment for him so the producers made him the next door neighbor instead. Secondly, and by far most notably, Michael Kenworthy was the first child actor and one of the only actors to turn down Aaron Spell!ng.

Michael was originally cast to play Brian Austin Green's part in Beverly Hills 90210 and had accepted the role for over 6 weeks only to change his mind at the last minute deciding that he wanted to go to college instead. On hearing this, Aaron Spelling attacked Kenworthy and effectively ended his career.
