They were a couple of TV movies done in the late 80's- not many folks remember them, or at least not many people I've talked to about them. I only managed to locate them after searching for John Rys-Davies, who I remember was interviewed about his role as the Kingpin. If it weren't for that scrap of memory, I probably wouldn't have managed to locate the ino, as I wasn't even sure if it featured the Bill Bixby/Lou Ferrigno combination in it!
On the same note, I think it's really cool that Lou has a bit part in each of the new Hulk movies!
