Rob Zombie's R-rated remake "Halloween" is on track to scare up a record-breaking showing at the Labor Day box office, grossing an estimated $26.5 million from 3,472 theaters through Sunday.

Long holiday weekend caps a boom summer for the film biz, with the domestic box office crossing the $4 billion mark Thursday night for the first time ever in a summer, according to Rentrak.

Bonanza even bled into Labor Day, generally not a busy movie-going frame.

Dimension's "Halloween," distributed by MGM, will wind up far outpacing the previous record-holder for best Labor Day opening, "Transporter 2," which grossed $20.1 million for the four days in 2005.

Zombie's remake is the first film in the horror franchise to debut away from the actual Halloween holiday.

Distribs will post official four-day estimates for the Labor Day weekend on Monday, with some providing three-day estimates on Sunday.

Coming in behind "Halloween" was Sony's holdover "Superbad." The R-rated teen laffer grossed an estimated $12.2 million from 3,002 locations through Sunday for a cume of $89 million.

In its debut, Rogue Pictures's sports parody "Balls of Fury" placed No. 3 as it grossed an estimated $11.6 million through Sunday from 3,052 locations.

Hyde Park Entertainment and 20th Century Fox's "Death Sentence," the weekend's other new wide release, grossed an estimated $4.2 million from 1,822 playdates for the three days.

On the specialty side, Lionsgate's "Ladron que roba a ladron" grossed an estimated $1.5 million from 340 locations in its debut for a per screen average of $4,447.

Also among specialty titles, ThinkFilm's "Self-Medicated" grossed $36,179 from 16 theaters for a per screen average of $2,261.
