Teenage Mutant Ninja Turtles, the fifth installment of the kids franchise, shelled the box office for $65 million.

Fond memories probably played a part in the film's success.  The studio says 55% of movie-goers were 25 or older.  61% of the audience was male.

The film obviously had greater-than-expected appeal to nostalgic parents.

The debut shattered analysts' expectations, which had hovered around $45 million.  Let's take a look at the Teenage Mutant Ninja Turtles trailer!
