8 pm: Theater

“Shockheaded Peter,” making its West Coast premiere, is based on a children’s book, but it’s definitely not for wee ones. This macabre staging of the 19th century “Struwwelpeter,” Heinrich Hoffman’s cautionary tales about disobedient children, is a mix of Grand Guignol, puppetry and Victorian melodrama, with songs by London’s underground cult trio the Tiger Lillies.

* “Shockheaded Peter,” UCLA, Freud Playhouse, Westwood. Tuesdays-Fridays, 8 p.m.; Saturdays, 5 and 10 p.m.; Sundays, 8 p.m. Ends May 28. $35. (310) 825-2101.

7:30 pm: Movie

In the decades since it opened in 1933, the Marx Brothers’ classic “Duck Soup” has gotten its due: It ranked 85th on the American Film Institute’s Top 100 movies, it’s on Leonard Maltin’s list of 100 Must-See Films of the 20th Century, and was added to the National Film Registry. “Duck Soup” is undeniably the Marx Brothers’ masterpiece, a political satire in which Groucho becomes the dictator of the fictional Freedonia and hires Chico and Harpo as spies. It’s also the last film Zeppo made with the team.

* “Duck Soup,” part of the “UCLA Film and Television Archive Presents: Archive Treasures” series. 7:30 p.m. at James Bridges Theater, UCLA, Westwood. $6. $4, students and seniors. (310) 206-FILM.

8 pm: Music

The Los Angeles Guitar Quartet’s new CD, “Air & Ground,” is a heady mix of string music that defies easy classification. The foursome--John Dearman, Bill Kanengiser, Scott Tennant and Andrew York--got together in 1980 at USC. They’ve toured the world but come back tonight to their namesake city.

* Los Angeles Guitar Quartet at Royce Hall, UCLA, Westwood. 8 p.m. $15 to $30. (310) 825-2101.

Noon: TV Museum
