A child actor who starred in commercials before landing his signature small-screen gig as Peter Brady on The Brady Bunch, he appeared in a handful of series — and numerous Brady spin-offs, TV-movies and variety shows — before more or less abandoning showbiz in the 1980s in favor of a career in the computer industry. His decision to appear on the "celebreality" series The Surreal Life in 2005 rejuvenated his professional and personal lives. Not only was he thrust back into the spotlight, he found love with housemate Adrianne Curry, and the couple soon earned their own reality spin-off, My Fair Brady, and married in 2006. Off screen, Knight has attention deficit disorder and has served as a spokesperson for the National Consumer League's AD/HD awareness campaign.
