Ordinary Decent Criminal is a 2000 crime comedy film, directed by Thaddeus O'Sullivan, written by Gerard Stembridge, and stars Kevin Spacey and Linda Fiorentino.

The film is loosely based on the story of Martin Cahill, a famous Irish crime boss.

Lynch finds himself in trouble when he is unable to sell a stolen Caravaggio painting, The Taking of Christ, giving Quigley the opportunity he was waiting for to try and catch him.

Having previously worked on Nothing Personal about loyalist paramilitaries, and a biopic about John Gotti for NBC, O'Sullivan did not want to again work under the factual and legal constraints of a film based on real people, and was more interested in making a comedy or caper, and instead they developed their own story only loosely based on Martin Cahill.

O'Sullivan was worried that investors might think the two projects were too similar, but after Boorman's The General screened at Cannes people saw the films were very different and were willing to invest.
