Curiosity alert. Isabella Rossellini wrote and stars in this collection of eight short films about bugs that have been airing on the Internet for a few months. Specifically, the childlike pieces are all about insect sex, how fireflies and spiders and the like actually fornicate. In each little piece, Rossellini dresses up in a bug costume and innocently describes the acts in detail.

Jon Hamm. I so want to make a green eggs joke.

Encore
Conventional but smartly paced, satisfyingly performed Brit caper comedy about trapped thieves hiding out in a convent disguised as nuns. Eric Idle, of Monty Python fame, suggests an English Gene Wilder with his bulging eyes and electrified hair, and roly-poly Robbie Coltrane is endearingly naughty as his larcenous partner. (PG-13; runs through July 31)
