The space 1999 footage would definitely qualify as they are unused or longer shots it would seem I will add it on now.
Ok let’s keep not of Battle Star Galactica for now.
One title I am highly suspicious of is Death Race and it’s sequel Death Race 2. I am almost certain the sequel uses loads of unused footage from the original films car chases and the splicing is so quick in the sequel it feels strung together with a bunch of deleted material somewhat.
You mean Death Race 2000?
