The movie omits the incest, thus omitting any hint of heterosexual interest, transforming Chris (Jeb Stuart Adams) into a gay-vague teenager. Grandma (Louise Fletcher) struts around with a Bible, accusing Chris and the other kids of "sin," which of course adds to the gay symbolism.
The incest angle, murderous relatives, and some nasty plot elements made the film controversial, but it didn't help Jeb's career.
Blond goldenboy Jeb Stuart Adam looked like he sprang up from the Appalachia of the Dukes of Hazzard, but he was actually the son of gay actor Nick Adams and his wife, Carol Nugent, and he grew up among the Hollywood glitterati.
His angelic smile and a smooth, firm but not muscular chest, making him perfect for roles as threatened kids: threatened by drug dealers on Quincy ME (1982), a bad father in His Mistress (1984), and a hippie cult on Airwolf (1985).
He also had significant supporting roles in The Goonies and Once Bitten, plus a 7-episode story arc (1977-78) on Baa Baa Black Sheep, about World War II fighter pilots led by Pappy Boyington (Robert Conrad).
After Flowers in the Attic, Jeb was threatened a few more times, in They Live (1988), Dragnet (1990), and Sworn to Vengeance (1993), but you can't play threatened kids forever. He retired from acting and moved into production design and stuntwork.
Today Jeb has a successful real estate business in Ventura, California, specializing in the million-plus market.
