The network is letting folks know now -- two weeks in advance -- that the premiere of its buzzworthy new series "Supernatural" will bleed over its one-hour allotment. The debut episode, which airs at 9 p.m. ET Tuesday, Sept. 13, will end at 10:07 p.m.

The "Supernatural" pilot runs just over 46 minutes, and that's without opening or closing credits. Hour-long shows typically are between 42 and 44 minutes long without commercials. Rather than cut a few minutes out of the pilot, The WB decided instead simply to let the show run long.
