I remember
Cage (1989) starring Lou Ferrigno who stars as a Vietnam War veteran named Billy who is shot in the head in battle and comes home from the war mentally retarded. I forget the plot points, but he somehow ends up fighting in cage matches (hence the movie title) and destroys people with his wrath and powerful strength when p**sed off, but if he's not p**sed off then he is a big ol' lovable teddy bear that you would trust your own little children to play games with.
The entire premise of the movie, I found to be extremely hilarious, especially the fight scenes where he goes from Teddy Ruxpin to rabid grizzly bear if someone punches the old war wound in his head! The first fight is the funniest, where Billy walks up to his mean opponent in the ring and happily introduces himself with an open handshake, "Hi, I'm Billy!" before he gets clobbered by his opponent and replies "Hey, why'd you do that?" The pummeling continues until you almost expect Lou Ferrigno to turn green before he inevitably mops the ring mat with his opponent's broken body.
Apparently,
Cage was so good that it spawned a sequel in 1994, but I never saw that one.
Cage is quite the gem and Lou's first big screen attempt at being recognized as a "serious actor". Of course it totally backfired
I think Lou Ferrigno's Filmography is interesting. Because of his Hulk reputation he should've been a bigger action movie hero star in the 80s. Instead he choose vanity projects showing off his physical assets rather than his acting abilities. Those glorifying Italian Hercules, Gladiator and Sinbad movies did nothing for him except for making him the laughing stock of bad movies. Had Lou been a bit more ambitious and serious about his movie career he should've started at zero playing the exact opposite of his Hulk stigma - as in the defeatable anti-hero or bad guy, and work his way up from there. His pseudo versatile image didn't come over well, though he did a decent job in the Matt Houston episode "Blood Ties" playing a serial killer.
Lots of missed opportunities and wrong (lazy?) career choices, that's why you won't ever see Lou in any Expendables movies
