F/X (also known as or subtitled Murder by Illusion) is a 1986 American action- thriller film about Rollie Tyler ( Bryan Brown), an expert in the art of special effects (F/X) with a reputation built by his work on many low-budget hack-and-slash films such as I Dismember Mama. The Department of Justice hires him to stage the murder of a gangster about to enter the Witness Protection Program. He agrees, but then things get complicated. Meanwhile, New York City police detective Leo McCarthy ( Brian Dennehy) is investigating the faked murder and cannot understand why the Justice Department is even less helpful than usual.
A sequel, F/X2: The Deadly Art of Illusion, was released in 1991. A spinoff TV series entitled F/X: The Series was produced from 1996 to 1998.
