While Fall doesn't officially begin until the end of September (and those who live in the City know that it doesn't really start until sometime in November), Fox is getting a jump on the other networks by starting their Fall premieres a lot sooner. Like, tonight soon. The network's much-hyped series Prison Break premieres with a two-hour episode this evening at 8 p.m. We were hoping to get a snazzy preview DVD in our latest issue of "Entertainment Weekly," but weren't that lucky, so we'll just have to base our suggestion on the proverbial word of mouth and, well, other's reviews.
