Carson began his career at a young age, acting intelevision advertisements, and later doing cartoon voice-acting for Hanna-Barbera. His first job was the voice of "Dino Boy/Todd" in 18 episodes of "Space Ghost" from 1966-1968, billed as Johnny Carson. He attended Los Angeles Valley College where he played a lead role in its 1969 production of The Taming Of The Shrew. Upon beginning his Hollywood career he was immediately engaged in a dispute with Johnny Carson over the use of their shared name - he subsequently went by the name John David Carson. Carson's first feature film was Pretty Maids All in a Row in 1971. Carson portrayed "Ponce de Leon Harper", a nerdy and sexually inexperienced young man who is tormented with lust at the pretty young women around him at school and suffers from chronic priapism. Ponce is eventually "mentored" by his guidance counselor, played by Rock Hudson, an expert at seducing younger women, who takes him under his wing and persuades an attractive female teacher to sleep with him. Another notable role was in the 1976 film Stay Hungry, alongside Arnold Schwarzenegger, Jeff Bridges and Sally Field. Carson also appeared in a great deal of television productions, including Hawaii Five-O and Charlie's Angels. He portrayed "Jay Spence" on Falcon Crest, a prime-time soap opera. He played "Larry Burns", a television repairman who is briefly framed for a woman's murder by a corrupt sheriff on Murder She Wrote and an Irish jockey named "Kevin Ryan" on Charlie's Angels. He appeared in various B-movies such as Empire of the Ants, an adaptation of an H. G. Wells story about gigantic, man-eating ants, Creature from Black Lake, Charge of the Model T's and The Fifth Floor, and acted alongside George C. Scott in The Day of the Dolphin. He again appeared opposite Scott, playing his character's son, in The Savage is Loose. Carson continued acting in small parts until 1990, appearing in the Julia Roberts hit Pretty Woman, which marked his last appearance on film. He voluntarily retired from acting after this role.
