How long is Avatar really?

IMDB says 162 minutes. Wiki says 161. Fandango says 150. How long is it really? And more importantly, why such a range of discrepancy?

I would guess 161.5 minutes including credits, or rounded to ~150 minutes not including credits.

I agree. It depends on if you count the credits or not. And the more CGI, the longer the credits.

That’s a rather personal question…

Just long enough to be the most expensive flop ever?

What odds are you offering? I have a few grand I could invest.

So did Cameron…
