Born in Santa Barbara, California in 1951, Timothy made his acting debut in Johnny Got His Gun (1971), a dramatic tour de force about a soldier who loses his arms and legs. He was very busy during the 1970s, but mostly in serious dramatic roles that I didn't see: Winesburg, Ohio (1973), based on the Sherwood Anderson stories; The Paper Chase (1973), about first-year law school students; A Small Town in Texas (1976), about a grifter in a small town in Texas.
During the 1980s and 1990s, he played mostly characters in small towns or the wilderness who hook up with women. However, he made up for it by taking off his shirt a lot. And by parodying President George W. Bush three times.
Unlike his brother, he has appeared in some gay-subtext vehicles: The Outlaw Josey Wales (1976), opposite Clint Eastwood, Apocalypse Now (1979), opposite Marlon Brando, and Hunter's Blood (1986), a Deliverance clone about evil hillbillies threatening some city boys.
He died in 2008.
Timothy and Sam may be the most famous of the Bottoms Boys, but there are two more:
In 1975, he became the only one of the Bottoms boys to appear nude in the gay-themed After Dark.
2. Ben, born in 1960, also appeared in Stalk the Wild Child, plus the anti-cult movie Blinded by the Light (1980), and a few more his brothers' vehicles.
