Two notable movies this weekend have a built-in track record and duos with some star power.

Emmy winner Tina Fey (SNL, 30 Rock) teams up with her old SNL co-anchor Amy Poehler for Baby Mama, about a career woman desperate to be, er, knocked up. The box office will decide how painful/joyful this birth will be.

Burger-munching stoner homies Harold And Kumar return only to find themselves knocked up, sorry, locked up in Gitmo in Harold And Kumar Escape From Guantanamo Bay. Special (?) appearance from Neil Patrick Harris.

This BlogPulse chart shows the rising buzz on both as the release date nears, with Fey getting an extra boost from 30 Rock’s recent return post-writer’s strike.
