Michael Jackson’s This Is It remained at the top of the box office for the sixth straight day on Monday. Sony’s highly anticipated concert documentary grossed $2.46 million for the day, which marked a 71 percent decrease from Sunday. That was a slightly larger daily percentage decline than most non-family films in wide releases experienced yesterday, though it was quite understandable given the film’s superb 18 percent daily increase on Sunday. Although This Is It opened well below the inflated expectations of most, it is already showing signs that suggest it won’t be anywhere near as front-loaded as it was originally expected to be either. This Is It has grossed $36.90 million thus far, placing it 50 percent ahead of the pace of 2004’s Ray (which was released just months after the death of Ray Charles).

Paramount’s Paranormal Activity finished in second with $1.19 million. That was down 69 percent from Sunday and down 36 percent from last Monday. After displaying tremendous holding power throughout the month of October, the low-budget horror film is starting to show some sings of slowing with Halloween now behind it. Nonetheless, Paranormal Activity has grossed $85.81 million in 39 days and is now just $14.19 million away from reaching the $100 million milestone.

Law Abiding Citizen continues to perform well for Overture as the action-thriller finished in third with $0.78 million. That marked a 65 percent slide from Sunday and a decline of just 27 percent from last Monday, though it should be noted that most holdovers experienced small declines from last Monday. The 18-day gross for Law Abiding Citizen stands at a better than expected $52.26 million.

Universal’s Couples Retreat finished in fourth place for the day with $0.59 million. The Vince Vaughn vehicle was down 68 percent from Sunday and down a slim 15 percent from last Monday. Couples Retreat has grossed $87.62 million through 25 days, placing it $12.38 million away from joining the $100 million club.

Where the Wild Things Are grossed $0.58 million to place in fifth. The big-budget production from Warner Bros. was down 75 percent from Sunday and down 31 percent from last Monday. Where the Wild Things Are has grossed $63.23 million in 18 days, which places it 11 percent behind the pace of 2001’s A.I. Artificial Intelligence (without adjusting for ticket price inflation).

The lackluster showing for Saw VI continues. The latest installment in the Lionsgate franchise was down 50 percent from last Monday with a daily gross of $0.44 million. The 11-day start for Saw VI stands at $22.98 million, which places the film on course to finish its domestic run with just a tad under $30 million.
