Watchmen Box Office Update has posted the box office estimates for this week, and while Watchmen managed to take second place its second weekend, it lost a lot of ticket sales:

Zack Snyder’s adaptation of the graphic novel Watchmen (Warner Bros.) took a nasty plunge from its strong opening weekend, dropping 67% to second place with $18 million in its second weekend. It has grossed $86 million in North America in its first ten days, though it will be a push for it to get to $130 million before it’s gone from theaters.
