Now this is a fun movie. I've always loved Jack Lemmon, especially for his turn in another Billy Wilder movie The Apartment, but this is like a perfect storm of talent. Him and Tony Curtis are a perfect set, playing off each other like the jazz musicians they're portraying, and Marilyn Monroe is pure sex. I'd been aware of her as an icon before, but this truly opened my eyes.
They don't make 'em like this anymore. Sure there's a bit too many coincidences, but that's all apart of the classic screwball formula. In fact, like Ebert says in his review, there's a lot of Shakesperean influence here, with mistaken identities and twists. In fact, here's Ebert's review, probably one of the best I've read by him:

He says it much better than I.
