The Queen Mary is hosting a special screening of the 1973 disaster-adventure movie "The Poseidon Adventure" in the ship's Exhibit Hall.

The evening begins with a silent auction of "Poseidon" memorabilia (proceeds will benefit the Queen Mary Restoration and Historic Preservation fund) and the screening will be followed by a question-and-answer discussion with several of the film's stars, including Shelley Winters, Carol Lynley, Stella Stevens and Pamela Sue Martin.

The Los Angeles County Museum of Art film program "Berlin Between the Wars" continues with a screening of director Josef Von Sternberg's 1930 erotic classic "The Blue Angel (Der Blaue Engel)," the film that made the sultry German actress Marlene Dietrich an international star. In the movie, Dietrich plays Lola-Lola, a cabaret singer who entrances and ultimately destroys a sober schoolteacher (Emil Jannings). Von Sternberg shot the film simultaneously in German and English. LACMA will screen the German-language version with English subtitles. Ilona Ziok's "Karussell," a documentary about the life of Kurt Gerron, a famous stage and screen comedian and character actor, will also screen. In "The Blue Angel," Gerron plays the seedy music hall promoter-magician who orders an indolent Dietrich to "get out there and sing!"
* "Berlin Between the Wars," LACMA, Bing Theater, 5905 Wilshire Blvd. Saturday: "The Blue Angel" and "Karussell," 7:30 p.m. The film series will continue on Friday and Saturday evenings through March 25. $5 to $7. (323) 857-6010.
