Henry made his film debut in "Curfew Breakers" (1957) and popped up on such series of the era as "77 Sunset Strip" (1963) and "The Adventures of Ozzie and Harriet" (1963) before being cast as a movie Tarzan in three American International Pictures films.
He got into the swing of things in "Tarzan and the Valley of Gold" (1966) with Nancy Kovack, "Tarzan and the Great River" (1967) with Diana Millay (who also died on January 8 of this year), and "Tarzan and the Jungle Boy" (1968) with Aliza Gur. Rafer Johnson, another jock-turned-thespian who appeared in the third film, died in December.
In what was a novelty at the time, the three Tarzan flicks were filmed back to back and released over time. Their popularity — it was said Henry most strongly resembled the character as envisioned by writer Edgar Rice Burroughs — led to a TV series, but Henry passed, allowing Ron Ely to take over.
Henry went on to appear in tough-guy roles in such films as "The Green Berets" (1968), "Rio Lobo" (1970), "Soylent Green" (1973), and "The Longest Yard" (1974), as well as on TV, making his next big impression in "Smokey and the Bandit" (1977) and its two sequels (1980 and 1983). In those wildly popular Burt Reynolds vehicles, he played Junior, the son of Sheriff Buford T. Justice, the great Jackie Gleason.
Henry's acting career tapered off, ending after he played a Russian baddie in "Outrageous Fortune" (1987).
In 1988, Henry retired due to his battle with Parkinson's disease and never made another public appearance.
