Another impressive weekend for film fanatics begins on Saturday, Oct. 1, 7 p.m., with the annual murder mystery double bill at Rome’s Capitol Theatre, 220 W. Domimick St. The 1936 Warner Oland entry Charlie Chan at the Olympics begins the program, followed by an interactive intermission that features a liveon-stage melodrama involving faux foul play, with the audience as sleuths. The evening ends with 1939’s The Cat and the Canary, a vintage Bob Hope mystery-comedy. Both films are presented in 35mm prints. Admission is $5.50 for adults, $1.50 for children under 12. Call 337- 6453 for details. Then on Monday, Oct. 3, 7:30 p.m., check out Bing Crosby’s most obscure film, the 1939 Paramount musical The Star Maker, a thinly veiled biography on vaudeville’s Gus Edwards, which probably hasn’t been seen locally since New York City’s WNEW-Channel 5 aired it on cable back in the 1970s. This Syracuse Cinephile Society offering screens at the Spaghetti Warehouse, 680 N. Clinton St., with a $3.50 admission for non-Cinephile members. For menu details, call 475-1807.
