The Wu-Tang Clan has never been shy about flaunting their influences: from martial arts to La Cosa Nostra, chess and, of course, superhero comics. But member Ghostface Killah’s love of one Marvel icon in particular, Iron Man, is putting the Shaolin rapper in some hot legal water.

According to reports, composer Jack Urbont is suing Sony Music Entertainment and Ghostface (born Dennis Coles) over claims the rapper illegally sampled his “Iron Man Theme” from the 1960s “The Marvel Super Heroes” TV show.

Ghostface, who named his 1996 solo debut Ironman, and whose many aliases include Ironman and the superhero’s alter ego, billionaire industrialist Tony Stark (which Ghostface spells Starks), has long had a fascination with the character. But Urbont claims in his suit that two songs on Ghostface’s second album, 2000’s Supreme Clientele copied “verbatim” the “Theme” he wrote for the show.
