Halloween. The season of costumes, trick-or-treating, and that classic American tradition: making something cheap and and selling it to the unwitting masses for a tidy profit.

This weekend Paranormal Activity 2 beat the Halloween weekend rush by opening a week early. The low budget horror/thriller was put together on a slim $3 million budget and earned back over $41 million in its first three days for an easy number one.

The $20 million Paranormal Activity 2 banked its first day was a record breaker for biggest opening day for a supernatural thriller, beating out the $14.8 million record held by sequel The Ring Two.

This weekend also marks the second in a row that a low budget sequel earned more cash than it deserved to be number one. Last weekend's champion Jackass 3-D dropped almost 60% from last week, but it was still strong enough to hold second place. Next week, it will likely cross the $100 million mark and break into the year's top twenty.

Clint Eastwood's latest offering, Hereafter starring Matt Damon, expanded from 6 theaters to over 2,100 and earned about $12 million. Not an exciting debut, but that's what you get when you try and market a drama as being somewhat supernatural during Halloween season. Horror fans can sniff the real thing from a mile away, usually by the lame plot and bad acting. Something from Eastwood and Damon has too much thoroughbred to fool those fans.
