Breakdancing...breaking...the break

Original Toronto Star caption: It's the scissors and the helicopter swipe and kids called the Mimico Flash, Don Mills Flash and dozens - maybe hundreds - of Something-or-other ''Flashes.'' It has made rivals of longtime friends Harry Belafonte and Sidney Poitier, both of whom will have breakdance movies out this spring. Belafonte's is called Beat Street, Poitier's is Shootout.
