Not to be a snake in everyone's boot, but the all-time opening weekend record is not in the bag for The Dark Knight just yet. The $155.3 million weekend estimate is just that -- a studio estimate -- and when the final numbers come out later this afternoon, Spider-Man 3's $151.1 million may still be on top of the heap. So everyone should chill for a few more hours.

Still -- $150 million! In one weekend! For a movie that's dark and scary and complicated and dead serious! That's pretty amazing, though my hopes for this wonderful film's box office staying power were dampened somewhat when I saw it a second time yesterday and heard the banter of the couple next to me, which consisted of statements like "Do you know what's going on? I don't know what's going on," and "I don't even understand who the bad guy is." (?!??) I guess you can't please everyone.

Anyway. $150 million +. First person to call it a disappointment because it's not the world's first $200 million opening weekend gets a kick in the crotch.

The weekend's counterprogramming saw mixed results. Mamma Mia!'s $27.6 million is an undeniable victory, though I think the market was begging for something not action- or family-oriented. I'm not sure what to say about Space Chimps' $7.4 million, seventh-place bow. I don't think anyone could have expected much more from a movie called Space Chimps.

The Dark Knight did a number on the superhero-themed holdovers, kicking Hellboy II down to the tune of 71%, and Hancock a somewhat gentler 57%. Hancock should see $200 million by the end of the week; Hellboy II probably won't get to $70 million domestic, though it should beat its predecessor's $60 million take.

The full top 10 estimates after the jump.
