Monday

Star trek A masterpiece of the genre, Howard Hawks' 1934 screwball comedy Twentieth Century is a perfect portrait of pompous theatrical hams in full honey-baked splendor. John Barrymore is hysterical as a histrionic Broadway producer who sets out to woo Carole Lombard, his one-time protege turned Hollywood star, back to the stage. When they both end up on the cross-country train that gives the film its title, he goes into his act, she goes into hers, and it's all sidesplitting. The film screens at 7 p.m. at the County Theater, 20 E. State St., Doylestown. Tickets are $8.75. Call 215-345-6789. The film also screens at the Ambler Theater, 108 E. Butler Ave., Ambler, at 7 p.m. Thursday. Tickets are $8.50. Call 215-345-7855.

Wednesday

Germantown via Saturn Though official records say he was born as Herman Poole Blount in Alabama in 1914, it wasn't difficult to believe jazz visionary Sun Ra's claim that he was actually from Saturn. After he relocated the ensemble/collective he called the Arkestra from Chicago to Germantown, it wasn't unusual to see him, attired in gold lamé robes, performing obscure solar rituals on the Wayne Avenue bridge over the SEPTA tracks. His time in Illinois is the focus of the exhibition Pathways to Unknown Worlds: Sun Ra, El Saturn & Chicago's Afro-Futurist Underground, 1954-1968, which collects paintings, drawings, prints, manuscripts, and video produced by and about Sun Ra and his associates. In connection with the exhibition (up until Aug. 2), musicologist John Szwed will discuss his study of the Sun Ra Arkestra at 7 p.m. at the Institute of Contemporary Art, 118 S. 36th St. Admission is free. Call 215-898-7108.

Killing machines The original terminator may have been Lee Marvin, cool and relentless as a mob assassin betrayed by his criminal cohort and bent on vengeance in John Boorman's 1967 classic Point Blank.

The films screen at 8 p.m. at the Rotunda, 4014 Walnut St. Admission is free. Call 215-901-3771.

Country girl When Rosanne Cash was 18, her father gave her a list of 100 essential country songs to learn - and since her father was Johnny Cash, this is a list we should all be interested in.
