In the real life story, John did not call Eddie Nash after the robbery at his place. Rather, John was spotted by some of Nash's associates in Hollywood. They noticed that John was wearing some of the jewelry that was stolen in the robbery and told Nash about it. John was then accosted by two gunmen who then took him to Nash for questioning.
Originally announced in 1998, the project at that time was going to star Michael Biehn (as John Holmes) and Tim Daly, with Nick Vallelonga in the director's chair.
The Chevrolet Caprice sedan that John Holmes was transported in to the hotel had the flush headlamps and the third brake light, making it a 1986 model.
In the beginning of the movie a character is seen using a "brick" mobile phone. The first mobile phone (the Motorola DynaTAC 8000X) was brought on the market in 1983 and therefore such a phone couldn't be in use in 1981.
David Lind: JOHN! He was the only one who knew about the Nash hit. That piece of shit ratted us out! Let Nash in and got my butterfly, Barbara, killed!
