His stunt performance in U.S. Marshals (1998) - the scene where Wesley Snipes escapes by swinging onto a moving train - Fontenot literally performed the stunt as it was seen in the film. He swung from the building on a 70 foot long reinforced cable and landed on the roof of a train station alongside a passing train. Because of the logistics of the scene, no safety net or airbag could be used, making it a one time only shot. It took ten weeks to plan the shot, and eight hours to set it up. It lasts for seven seconds in the film.

Has a black belt in Kyokushin. Also trained in boxing, Kickboxing, Goju, Shotokan, and is good with the use of weapons.
