"The Mexican" is Surround EX-encoded (and also DTS-ES compatible). Gary Rydstrom was the lead re-recording mixer, and he has used Surround EX in every film he's worked on since "Star Wars: Episode I." He's very much in favor of it.
One of the annoying aspects of Surround EX is that it's not always easy to know what films actually used it. It's certainly possible for a post facility to have used it for a certain soundtrack and Dolby or no one else knowing about it. "The Mexican" is one of these films, as was "Hollow Man" and others.
If someone out there can convince me through reputable sources that "The Claim" was Surround EX-encoded, I'd greatly appreciate that.
