Although 30 Rock still struggles to compete on Thursdays, Tina Fey’s Baby Mama had no problem topping the competition.  The film, co-starring Amy Poehler, earned $17.4 million and made a showing for women everywhere.  When’s the last time a movie with two female leads debuted at #1?

Interestingly enough, Mama‘s screen average ($6845) was outdone by another female-centric movie: The She Found Me.  The movie that was directed and written by star Helen Hunt earned $8066 per screen this weekend.  Fairly impressive considering Found, also featuring Bette Midler, opened in 44th place.

Friday’s other big entry - Harold & Kumar Escape From Guantanamo Bay - came in second place with a $14.9 million take.  Surprisingly, that gross nearly equals what the original film raked in during it’s total run.
