Memorial Day weekend at the US Box Office tends to generate big winners. This year, there are winners but they are more average rather than anything else with two big entries failing to really take off as other blockbusters have in the past.

Opening in first place is Ben Stiller's NIGHT AT THE MUSEUM: BATTLE OF THE SMITHSONIAN. Earning $54M over the Friday-Sunday portion of the weekend, the film has done very well to open over its major challenger TERMINATOR SALVATION, which debuted in second spot with a somewhat underwhelming $42.5M. Both films have had a decent start but not the one their respective distributors would have been looking for, particularly in the case of TERMINATOR SALVATION which has to now be considered a non-event given its $200M budget and horrendous word of mouth likely to affect its overall box office in the coming weeks.

Third place film STAR TREK is perhaps the unlikely winner of the weekend in the sense that it beat out ANGELS AND DEMONS to score a solid $22.8M in its third weekend of release. The sci-fi reboot is still doing remarkably well, closing in on $200M domestic and will cross that next weekend. As for ANGELS AND DEMONS, the Tom Hanks "thriller" is following the same trajectory as its predecessor THE DA VINCI CODE, but with far less money in the kitty. However, overseas grosses have already put this film in to the black so distributor Sony will not be too displeased at this point.

Lost in the flurry but still earning a decent amount is another new opener DANCE FLICK, which somehow managed $10.6M over the Friday-Sunday portion of the weekend. Yet another spoof, the film has shown that this genre still somehow has an audience and will likely do well at recouping its $25M budget.

X-MEN ORIGINS: WOLVERINE is still holding on, earning another $8M in box office over the weekend. The film has earned over $160M now, but given its massive debut, and the fact that STAR TREK has earned more in less time appears to have taken the gloss over this respectable gross.

The US Box Office took in a total of $169,439,000 for the whole of the weekend 22-24 May 2009. The US Box Office took in an additional $47,057,000 on the Memorial Day Monday.
