Because of his 6 ft 6 in (1.98 m), 300 lb (140 kg) frame, Longo was often chosen for roles that depict him as an imposing giant with freakish strength, and sub-standard intelligence, such as Mad Dog in the 1980s comedy/drama 1st and Ten where he was a linebacker for the fictional football team, the California Bulls. Mad Dog was paired with fellow linebacker Dr. Death, played by actor Donald Gibb who has had a career playing similar roles as Longo. He also appeared in Suburban Commando starring Hulk Hogan as a bounty hunter alongside The Undertaker.
Longo died in his sleep at his home in Marina del Rey, California on June 21, 2015 after a long battle with congestive heart failure and kidney issues. He was survived by daughters Chloe Longo, Danielle Schramm, stepdaughter Alexis Dejoria and wife of 23 years, Jamie Briggs.
