ABC has put the pilot for their new show, “Last Resort”, online for those who can’t wait until the 27th (or who welcome the chance to watch without commercials):

Andre Braugher is captain of a nuclear sub who refuses an illegal order, the US government tries to kill his sub and everyone on it, conspiracies and action and war and and and… Tom Clancy-ish with 24-style inside-our-govt villains, looks pretty awesome. Writer/producer is Shawn Ryan (“The Shield”)

NBC’s “Revolution” is also online early, but there’s as many commercials on the network website as there’d be watching it on broadcast.
