A former producer is taking on Staten Island’s Wu-Tang Clan.

Former Wu-Tang producer Selwyn Bougard claims the group, including brothers Mitchell and Robert Diggs, owes him more than $500,000 in unpaid royalties for his work, according to a Manhattan Supreme Court lawsuit.

He’s never received an accounting of how much the music has earned, Bougard claims in court papers.

Bougard knew there was a problem nearly 20 years ago “but he was young and looked up to them and he had no representation and was unable to collect,” his lawyer, Kevon Glickman said. “He finally has representation and we hope to get him properly compensated for his music.
