Was Sacha Baron Cohen (Ali G) the guy who played SUPERGREG?

You may or may not remember the supergreg frenzy on the internet about 5 years ago . Refresh your memory here:

That came up in coverasation with a coworker today, and he said he thought it was Sacha Baron Cohen (Better known to the world as Ali G) who did the supergreg acting. I didn’t think it was, but in watching this, I’m now not sure. It looks like it could be him.
Anyone know for sure?

Pictures here if you don’t have quicktime.

His IMDb trivia section doesn’t mention anything although a couple google searches show that a few people believe they’re the same.

Nothing more conclusive than that though, sorry.

I’m a big Sacha Cohen fan, and I say that they’re not the same person. They don’t look alike to me.

Peace.

I’m pretty sure it’s not him, unless he did some serious makeup.

I don’t think it’s him, either. Sasha is very tall, and this guy looks on the short side to me. He’s also nowhere near as good-looking as Sasha. Just a look-alike.
