it would be funny to have seen a double of an original and what tarintino riped off, i mean paid for.

Tarantino, ripped off? I don't get the joke? Are you saying all his films are rip offs from other films? I only have a few that one with Brad Pitt on bluray the other one with Bruce Willis as Butch on DVD R2 and the one with dogs on PAL laserdisc and that's about it.

I was looking at an eBay sale of double sale and thought well that one makes sense.

The Abyss (1989) + Leviathan (1990) and yes I know there is DeepStar Six also.

Or maybe how about if I switch them around.

The Abyss (1989) + DeepStar Six (1989)

ALIEN (1979) + Leviathan (1990)

Ha, talk about Tarentino's rip-off...

How about Alien and It, The Terror From Beyond Space...

The courts agreed it was a theft.

But you have to watch It first, and then Alien to appreciate it.
