Is there an extended cut out there of the thing using the deleted scenes or some of them?

Not only that but the prequal has some potential scenes to extend the introduction.

I have not seen the prequal and actually don't want to... But I ran across these and thought hmmmmm....

I would remove the subs though for sure... And only a quick flash of the burnt thing in the ice.

The original deleted scenes

Although I think the film is fine as it is... It's just conjecture.

For any fans of the thing though this is a must watch
