Can ‘Shutter Island’ keep it up?

The news regarding “Shutter Island” involves its estimated $40 million take at the box office. That’s all well and good, though it’s likely to tail off as the week progresses. And Friday’s releases , the Bruce Willis-Tracy Morgan comedy “Cop Out” and the zombie flick “The Crazies,” should cut into its future earnings.

So while we Scorsese fans are celebrating for the moment, “Shutter Island” - which has been in the can since October - has a ways to go to earn back its estimated $80 million production costs. By the standard formula , “Shutter Island” has to make at least $200 to break even.

Wonder where Hollywood accountants go to school? Disneyland?
