Ty's movie picks for Friday October 23

Chris Rock in "Good Hair," opening today

Two local doings this weekend --

The Boston Bike Film Festival comes to the Brattle today and tomorrow. If you push a bipedal piece of metal around the city on a regular basis and/or want to make Boston better for bikes, it's worth checking out this high-spirited collection of shorts, videos, films about the bicycle lanes on Comm. Ave (now they're talking my language) and even an auction. Here's the schedule -- Mayor Menino, I expect to see you there, with helmet.

On Saturday over at the West Newton Cinema in, um, West Newton, the director of the excellent inner-city-school documentary "Heart of Stone," Beth Toni Kruvant will host a Q&A after the 3:45 and 6:15 shows. The film's also playing at the MFA.

Among the major new releases, "Amelia" is a big, glossy, half-empty bio of Amelia Earhart starring Hilary Swank. "Astro Boy" is a slick, half-full CGI attempt to rescuscitate the beloved manga/anime figure. "Cirque du Freak: The Vampire's Assistant" is an interesting male "Twilight" variation sunk by a boring male ingenue and a fun but not particularly scary John C. Reilly. That leaves the genital-mutilation hijinks of "Antichrist," Lars von Trier's latest blow against the empire -- remarkable moviemaking, deeply screwed-up gender politics, laughable pretensions even when they work. Oh, that Lars. "Motherhood," the Uma Thurman comedy, is a dud says Wesley, but the secret sleeper of this weekend may be Chris Rock's "Good Hair," about the triangular relationship between black men, black women, and black women's hair.
