The last weekend of spring break packs in one last blockbuster with hopes of packing them in before they head back to school — college, mostly — since the film we’re talking about is “G.I. Joe: Retaliation.”

Will this 3D actioner blow up? Will it exceed the similarly explosive “Olympus Has Fallen’s” take from last weekend?

Variety thinks that Wednesday night’s $2.2 million midnight show opening predicts a $45 million weekend.

The Box Office Guru is thinking it’ll clear $41 million. Maybe. It opened late Wednesday night, and could have a long, fruitful weekend ($49 by Monday AM, the Guru thinks).

Box Office Mojo figures “G.I. Joe” will do a robust $37 million.

Tyler Perry’s new one doesn’t break formula. Well, Madea isn’t in it. His “OTHER” formula — women in crisis.

Box Office Mojo predicts this will do mid-range Tyler Perry business — $18 million. His “Madea” movies have occasionally hit $30.

Box Office Guru thinks only $16 million for this one.

“The Host” is already suffering from awful reviews. It’s sure to be a post-‘Twilight’ let down.

Box Office Mojo is already raining on “The Host,” figuring it won’t hit $15. The Guru figures it’ll clear $15.

“The Croods,” if the crowd I saw leaving the multiplex last night as I waited to watch “Temptation” is any indication, will do another $25-30 million this weekend.
