The Boulder showings include a couple of sonic layers designed to bolster the flickering black-and-white images. The versatile Hank Troy provides live musical accompaniment, just as genuine pre-talkie musicians did for films way back when. And series organizers encourage good, old-fashioned hissing and cheering by viewers, which livens up the gathering. Think Rocky Horror without squirt guns and toilet paper.
Tonight's 7 p.m. show is a double bill: Laurel and Hardy's Big Business, a 1929 goof about the duo selling Christmas trees in July, is paired with Charlie Chaplin's Gold Rush, a 1925 vehicle that allows the Yukon-bound Little Tramp to chew on plenty of comic fodder (including a stewed boot).
The films are shown at the Chautauqua Community House, 900 Baseline Road; admission is $5 for adults, $4 for children and seniors. For more information on the monthly series, which runs through April, visit www.chautauqua.com. -- Ernie Tucker
