District 9 may not have have any big name stars and it may not be based on a story everyone knows, but it does have something no other film has this Monday: a first place finish.

Over the weekend, the R-rated actioner landed on Earth safely with over $37 million in ticket sales. The sci-fi entry also raked in one of the best per screen averages ($12,251) of any film currently in in theaters. (Sony Pictures Classics’ It Might Get Loud averaged $13,240 while in limited release.)

In the non-alien department, The Time Traveler’s Wife cornered the romantic genre with an $18.6 million total. Meanwhile, Vanessa Hudgens proved she’s nothing without her better half. The Disney star’s new film, Bandslam, failed to even crack the Top Ten. The teen comedy barely managed to gross over $2 million.
