Definitely, Maybe (2008) (nat)

A cute romantic comedy (although Joel takes issue with my putting it in that genre). Maya (Abilgail Breslin) asks her dad, Will Hayes (Ryan Reynolds), to tell her the story of how he got together with her mother after she's learned about sex in school that day (it's also prompted by the fact that her parents are divorcing). He tells her a long story about his dating three girls-- Emily (Elizabeth Banks), Summer Hartley (Rachel Weisz), and April (Isla Fisher)--and doesn't tell Maya which woman is her mother so she has to figure it out. The poor guy is not so much lucky in love but I can't so much tell you how. Everybody does a wonderful job with the acting and whatnot--which is impressive in this case because the viewer has to constantly change his/her opinion of the characters. Anyway, it's super-cute and fun to watch and very satisfying as a romantic comedy.
