On the heels of 'Law & Order's' cancellation, NBC announced today that it has picked up four new series for next season -- three dramas and one comedy -- and will be parting ways with newbie medical dramas 'Mercy' and 'Trauma.'

Among the dramas headed to the Peacock net is 'The Cape,' starring 'ER's' David Lyons as a policeman who is framed for a series of murders and is forced to go into hiding. Determined to be reunited with his family, Lyons' character becomes his son's favorite superhero ('The Cape') and quickly "takes the law into his own hands."

Meanwhile, 'West Wing' alum Jimmy Smits will return to the network in the drama 'Outlaw,' about a Supreme Court justice who quits his job to go work for the little man.

Rounding out the list of dramas is the latest legal series from David E. Kelley ('The Practice'; 'Ally McBeal'), 'Harry's Law.' The show stars Oscar-winning actress Kathy Bates as a lawyer who unexpectedly starts her own firm with characters portrayed by Brittany Snow and Ben Chaplin.

'ER's' David Lyons, Shane West and Laura Innes have each booked pilots on NBC and the CW. According to reports, Lyons will lead NBC's 'The Cape,' about an ex-cop who becomes a superhero in an attempt to fix his reputation and reunite with his son. Over at the CW, West will join Maggie Q in the upcoming reboot of 'Nikita,' while Innes will create an 'Event' at NBC, playing the head of the inmates at a "secret facility." [Hollywood Reporter]

More casting news after the jump.

Reading a quick description of Day One and seeing this behind the scenes footage, I think this might be NBC's version of Jericho. That's probably the show that this will be compared to, though this one looks more action-oriented. It's from ex-Heroes/Lost/Alias writer/producer Jesse Alexander, and it's about a group of people from an apartment complex in Van Nuys that have to band together when something mysterious happens to the planet.
