This is probably more helpful than the current MPAA rating system in use here. Via the Washington Post:
Four Swedish movie theaters touched off a heated debate across Stockholm last month — and in the English-language media this morning — with the announcement that they plan to begin publicly labeling films that pass the so-called “Bechdel test.” The metric gauges whether a film meets a bare minimum standard for developed female characters.
Promoters are encouraging theaters to stamp its “A” logo on the movie posters and pre-roll screens of any film that (1) has at least two female characters who (2) talk to each other (3) about something other than men. A surprisingly high proportion of films fail this test.
In the weeks since, it has been covered in a dozen newspaper columns and earning the endorsements of Equalisters, Women in Television and Film and a popular cable movie channel and, controversially, the blessing of Anna Serner, who presides over Sweden’s state-funded film institute.
