The WAM! (Women, Action and the Media) Film Festival is back from a one-year hiatus with another batch of work by and spotlighting promising women in film from around the world. There are two sessions of dramatic short films (from noon to 1:15 p.m., focused on family dynamics) and from 4:30 to 6 p.m. (focused on change and transformation). A free Boston Film Industry Panel runs from 2 to 3:30 p.m., and the feature film, “Red Lines,” about two young activists risking their lives to take part in the Syrian Revolution, runs from 7 to 9:30 p.m. Information is here.

North Cambridge Family Opera’s “Kids Court” at 3 and 7 p.m. Saturday and at 1 and 5 p.m. Sunday at the Peabody School at 70 Rindge Ave., North Cambridge. There is a suggested donation of $10 for adults and $5 for kids.

If you live in Cambridge, you’re bound to know someone in this show’s crew and dual cast. The musical, which premiered in 2007 (see clips here), is a spoof on reality TV in which Judge Trudi hears the case of Hansel and Gretel, interrupted occasionally by spoof commercials for products and services. Family Opera shows are generally bright, funny and entertaining – a sweet 90-minute gift for parents and kids – but this show will amuse with its slightly darker tone. One song is even called “Some Children Should be Drowned at Birth,” a Family Opera parent reports. Information is here.
