IM Global genre division Octane has come aboard to fully finance Andrew Lau‘s mean streets thriller Revenge Of The Green Dragons. Lau directed the original Hong Kong trilogy Infernal Affairs upon which Martin Scorsese‘s Oscar-winning The Departed was based. The pic now has an April start date, and Scorsese as exec producer.

It’s set in 1980s New York and follows two immigrant brothers who join the Green Dragons gang and quickly rise up the ranks, becoming notorious to the city’s police. When an ill-fated love affair pits one of the brothers against the gang leader, he sets out for revenge on the group. The film is based on the true story of the real Green Dragons gang which was chronicled by the New Yorker‘s Frederic Dannen in 1992. Michael Di Jiacomo wrote the script. Scorsese is exec producing with Deepak Nayar, Steve Squillante, Michael Bassick and Art Spigel. Lau, Andrew Loo, Stuart Ford, Ara Katz, and Allen Bain and Jesse Scolaro of 7th Floor Productions will produce.

Bain said today, “When I first discovered Dannen’s true-crime expose of a neglected side of the American Dream, I knew instantly it had to be adapted for the big screen. We are very excited to partner with IM Global and Stuart Ford in bringing this action packed and gripping story to life.”

The deal was negotiated between Ford and SVP Business & Legal Affairs Elizabeth Powell for IM Global, and Bain and Scolaro, represented by attorney Iddo Arad at Frankfurt Kurnit Klein & Selz. Lau is represented by Brian Levy at New School Media and Bianca Levin at Gang Tyre Ramer and Brown. Scorsese is repped by WME.
