Matt Damon was spotted meeting with Harvey Weinstein and “Ocean’s 13” screenwriters Brian Koppelman and David Levien at Cipriani Downtown, to start a script on their poker movie, “Rounders 2.” Edward Norton will join the sequel, sources say. In “Rounders,” Damon played a law student dragged back into gambling by an ex-con pal. The 1998 movie was a box-office dud but became a DVD hit. Meanwhile, Damon’s rep said after repeated calls about his postponed Anthony Weiner fund-raiser, “He’s traveling, and I can’t reach him.”
