Following the web shorts created for American Express that we recently reported about, it has been announced by Variety that “NBC will air The Adventures Of Seinfeld And Superman from 8:44-9 pm on May 20. The special will mix original Seinfeld-Superman footage with elements from the Internet shorts. There’s no word yet on whether Amex is paying for the airtime, or if NBC simply views it as a way to get Seinfeld back on NBC”. The full story is relayed via SciFi Wire, and thanks to Shawn for the heads up!
