i stand corrected, gentlemen! Jay-Z was not in the Substitute. and apparently, the guy's name in the movie is Jerome, as opposed to Tyrone.
fuck!! i guess my Substitute trivia just isn't up to par.
funny side note: when i was back in college, my brother and i got real stoned and went out and rented all of the Substitute movies, just for a good laugh. we got through the first one,,laughed our asses off, of course. all the while higher than hell. then, we got to the second one, i think it was starring Treat Williams in place of Tom Beringer. it was so horrible, we had to turn the tv off. we couldnt even watch it.
