There's an interview with Eric where he explains why it turned out this way. They were given (supposed to be given?) quite some money for that, but their management didn't strike a deal with the producers or something and they ended up appearing for less than a minute only. I can't remember really, but it's out there, somewhere in the Internet.
I was wondering if any of Testament's songs was ever used in a movie. They sure have some that would fit various types of films- from ballads through groovy rock-based metal to ultra-heavy thrash/death monsters. Anyone ever spotted anything? 'Cause if they appeared in a movie, we'd probably know about it. But there must have been at least a song. I hope there will be some day. Would be cool to see that happen.
