1. Martial arts. Bruce Lee in Enter the Dragon (1973), the song "Kung Fu Fighting" (1974), the tv series Kung Fu (1972-75).
2. Truckers. The song "Convoy" (1976), CB radios, trucker lingo ("10-4, good buddy."), Smoky and the Bandits (1977), The Dukes of Hazzard (1979-85, although they actually drove a race car).
Inevitably they were combined in Breaker, Breaker (1977), starring 37-year old martial artist Chuck Norris, who played Bruce Lee's opponent in Way of the Dragon (1972), and would go on to a successful career as a man-mountain.
But fortunately, The Girl gets on her CB radio and notifies the other truckers, who rush to the rescue and tear the town apart. That's Trucker Justice.
I loved this movie when I first saw it, during my junior year in high school. I don't anymore. It's very, very bad. But it has lots of gay subtexts.
2. J.D. and Billy have an effusively physical relationship.
3. Billy doesn't express any interest in women.
4. There are lots of shirtless scenes.
But don't tell Chuck Norris: today he's a vocal homophobe and all-around right-wing nutjob.
On stage, he starred in A Christmas Carol, Hairspray, and The Weir in Colorado Springs.
According to his Facebook page, he likes Bill Maher, Ram Dass, Democrats, and Move On.org, and Chuck Norris is not on his "friend" list. I'm going to guess a gay ally.
