Murder by Illusion

Rollie is an expert in the art of special effects (F/X) and has a reputation built on many low-budget hack-and-slash films (including such titles as "I Dismember Momma") and is quite surprised to find that the FBI has a job for him. He is to stage the murder of a gangster who is about to enter the Witness Protection Program. He agrees, but then things get complicated. All the while, a New York City police detective, Leo McCarthy, is investigating the faked murder and can't understand why the FBI is even less helpful than usual.
