L'ange noir

I, too, saw this film on "Commander USA's Groovie Movies" when I was a kid. I don't remember much about it, except that it had a terribly complicated plot and contained almost no suspense or horror to speak of. The one thing I remember about this film (one that I can't forget) is "Mikey" one of the main character's sons. "Mikey" was this creepy red-haired kid who, for some reason, spoke entirely on a post-synchronized soundtrack (with his heavily Canadian-accented voice dubbed in by what was obviously an adult mimicking a kid's voice). In one scene, he climbed on top of this glowing coffin and said, "I like you, you're nice and bright! Want me to climb in??!" He then climbed into the coffin and disappeared for the remainder of the film. Odd.
