Friday the 13th makes a killing at the B.O!

Gory “Friday the 13th” carved its way to the top of the holiday box office, earning a record $42 million on its opening weekend.

The remake of the 1980 horror flick set an all-time high for scary movies, edging out 2004’s “The Grudge,” which raked in $39 million during its debut weekend.

The machete-madness movie features hockey-masked zombie Jason, a drowned summer camper who takes revenge on a new generation of frisky teen counselors.

Even with Valentine’s Day falling on Saturday, “Friday” easily routed the chick flick “He’s Just Not That Into You,” which fell to second place with a take of $19.6 million.

The thriller “Taken” fell to third, with $19.3 million in ticket sales.

Among other new movies, the comedy “Confessions of a Shopaholic” landed in fourth place with sales of $15.4 million, while “The International” pulled in $10 million to finish seventh.

Hollywood was cheering what looks like the best Presidents’ Day weekend ever at the box office. The total gross of all movies was about $190 million, which trumps the previous benchmark of $157 million set in 2007.
