On the strength of surprise hit “Double Jeopardy,” Paramount won the October B.O. race with 21% of the total take. Overall grosses of $505.2 million rose 11% over the same month in 1998.

Warner Bros. finished No. 2 with 15.9% of receipts thanks to the healthy bows of “Three Kings,” the studio’s best ever in October, and “House on Haunted Hill.”

Despite stumbles like “Random Hearts” and “Crazy in Alabama,” Sony finished third in market share for the month, at 13.6%.

‘Jeopardy’ No. 1

Top title of the period was “Double Jeopardy,” with $68.1 million. Released Sept. 24, the Ashley Judd starrer has a cume of $98.3 million.

Next was “Three Kings” with $53.7 million. DreamWorks’ “American Beauty” opened as a platform release Sept. 15 and in October, it grossed $43.9 million.

“The Sixth Sense,” Disney’s August chiller, was fourth at $32.3 million, followed by “Random Hearts” at $29.5 million.

Punctuation mark to the month was unexpected Halloween treat. Overall biz spiked more than 20% over last year. Studios often shy away from the frame amid concerns about partying and haunted houses sapping B.O. totals.

But weekend bow of “House on Haunted Hill” turned out to be $15.9 million — best ever within two days of the holiday.
