Audiences prone to going to a movie’s opening weekend are even more prone to dash off to a movie they’re dying to see late night Thursday or Friday.

Especially with regards to summer popcorn pictures.

So…”Godzilla” shot his wad Friday.

Saturday? A 20% drop off, despite having more people off from work and a whole day of screenings available.

It won’t hurt the film, but it does suggest that there is a finite audience for this big lizard blockbuster.

People were talking $100 million for the big guy in box office discussions Saturday afternoon.

Sunday AM? $90-92. (UPDATED — final estimate, $93.2)

Reviews, which tilted toward ecstatic on Tuesday have settled down to “It’s OK, especially if you’re a kid movie goer.”

“Neighbors” is still settled in at number 2, “Million Dollar Arm” is still looking like a $10 million opening weekend. Audience scores tracked leaving that one have been quite high, so word of mouth will help the Mouse in weeks to come.

“Belle” and “Chef” are doing very well in limited release, “Heaven is for Real” and “Mom’s Night Out” are still in the top ten.

“Godzilla” will only enjoy one weekend at the top. “X-Men Xterminate All Lizards” opens next week.
