Will Smith's new movie Hancock has been accused of homophobia by gay rights campaigners.Bosses at The Gay & Lesbian Alliance Against Defamation (GLAAD) allege a scene in the superhero movie takes a "cheap, unfunny shot at gay people".The offending scene involves Smith's washed up crime fighter dismissing other superhero images, saying, "Homo. Homo in red. Norwegian Homo."GLAAD chiefs claim "the slur sends a message that it's okay to discriminate against gay people".Representatives for Columbia Pictures, the studio behind the movie, have refused to comment.
