If you weren't already tired of the late-August movie "dog days," last Friday gave us three more movies that weren't pre-screened for critics: "Babylon, A.D.," "College" and "Disaster Movie." And next weekend holds "Bangkok Dangerous," which looks dreadful.

But there are still some options out there for audiences that have already seen the better summer hits "The Dark Knight," "Iron Man" and "WALL• E."

For example, would-be crooners can now participate in something called "Mamma Mia!: Sing-Along Edition." Select theaters, including Megaplex Theatres' District and Jordan Commons locations, are showing the musical in a subtitled format that encourages audience participation.

• THE GANGRENE FILM FESTIVAL. Despite its rather unsavory-sounding title, the annual event boasts screenings of comedy shorts, stand-up comedy performances and musical concerts. Most, if not all, of it is family-friendly.

Layton's Ed Kenley Amphitheatre, 403 N. Wasatch Drive, hosts this year's event on Friday. A "general audience" session starts at 8:30 p.m., and the "late session," with slightly edgier material, follows at 11 p.m.

Tickets are $7, or $10 for both sessions. More information on the festival can be found at www.gangrene
