are there different versions of Movie 43 in the UK and the US?

This was nowhere near anything I saw in Movie 43:

Nowhere near.

It also makes me very sad to know that Greg Kinnear has any connection this awful film.

I think this could be the most egregious difference between international versions of a film ever. There are often small differences, often made to appease local censors. (I think The Hunger Games may have had a bit of blood splatter cut out for U.K. audiences that was left in for U.S. audiences, for example.) But this represents entirely different stories presented to various audiences. I don’t understand the rationale behind this, and frankly I’m pretty pissed off that I’ve been forced to think about Movie 43 more than it deserves.
