Well I saw it yesterday. I really enjoyed it, my favourite comedy of 2008 alongwith Walk Hard. Carrell & Hathaway were both great. I also never minded Dwayne Johnson in this, he usually annoys me but he wasn't too bad. Alan Arkin, Terrence Stamp and James Caan were all pretty good too.
i liked Arkin and Caan, but Stamp annoyed me, mostly because he didn't play Siegfried anything like the original... i've never really had a problem with Dwayne Johnson, but sometimes the movies he chooses to do aren't good choices... at least this one was a good choice!
anyway, glad you liked it! you should come join my Get Smart community...
I'll have to buy the first of the original series. I like what I've seen from the odd episodes on Youtube, so I'll wait till one pops up on ebay (and I've got some £££)
Going back to the 08 movie, another great scene was with Arkin & the Swordfish. Peter Segal did that in his movie My Fellow Americans but instead of a swordfish it was a giant snowman's face going through a car window.
