Three buddies and a caper are all it takes to make a good crime yarn—throw in some character clashes and a philosophical difference or two, and you’re headed straight to DVD with the best of ’em. That formula has certainly propelled plenty of Hong Kong action films, but 2007’s Triangle dares to think a little bigger, featuring three buddies and a harebrained scheme—plus three Hong Kong cult kingpins directing to boot. Tsui Hark invited Ringo Lam and Johnny To to work on this tale of triads and treasure hunters, with each directing a 30-35 minute segment. The styles of each part are different, which you don’t expect, but there’s still a philosophical difference or two, which you do. It shows as part of the Made in Hong Kong Film Festival. TRIANGLE SHOWS AT 2 P.M. AT THE FREER GALLERY’S MEYER AUDITORIUM, 12TH ST. & JEFFERSON DR. SW. FREE. (202) 633-4880.
