Actor/director Tyler Perry has threatened legal action against his producer cousin MARLON CAMPBELL - after he used the star's name to help promote his own film OBLIVIOUS.
Campbell claims Perry's lawyers sent him a letter warning him against name-dropping to try and raise the profile of his own movie.
According to website TMZ.com, the letter says any connection linking Perry to Oblivious is "intentionally misleading" and "wrongfully infringes up the economic value of Mr. Perry".
