On Sunday, the film adaptation of Prince of Persia: The Sands of Time could only manage a third place finish in its first three days at the box office in the US. However the movie managed to move up a spot in its latest box office results which include the Memorial Day numbers.According to Variety, the movie based on the action-adventure game series brought in a total of $37.8 million for the four-day weekend in the US. That puts it in second place ahead of Sex and the City 2 which generated $37.1 million in revenues for the same time period. Both movies were still well behind the first place film Shrek Forever After which claimed $55.7 million for the four day weekend. Keep in mind that these are estimates; the final numbers won't be known until Tuesday. As we reported on Sunday, the Prince of Persia movie is doing much better overseas with box office numbers that overall are nearly twice as much as the movie has made so far in the US.
