What's that? Nathan Fillion back on my TV screen? Indeed. Fillion is preparing to return to TV in Castle, an ABC crime dramedy that will debut sometime later this season.

Meet Richard Castle, a successful murder-mystery writer who has just killed off his main character. But it seems one of his fans liked his livres a bit too much when a copycat murderer starts killing people as described in Castle's books.

“Castle” is a 1 heure witty drama that will air on Monday nights at 10pm beginning March 9th, 2009. “Castle” based on a famous crime and horror novelist, Rick Castle, who helps the NYPD homicide department solve crimes.
