As if '17th Precinct' didn't sound wonderful enough already, today comes news that yet another 'Battlestar Galactica' veteran has booked a role in the NBC pilot.

James Callis, otherwise known as 'BSG' scientist Gaius Baltar, will work alongside former costar Jamie Bamber in the series, Deadline reports.

The series, headed by 'BSG' mastermind Ron Moore, follows cops in a world where magic is real -- think 'Harry Potter' meets 'Law & Order.' Also on board, according to Deadline: former 'The Deep End' star Matt Long.

Several other stars booked pilots, including 'Greek' star Amber Stevens, who will play a psychiatry intern on 'Weekends at Bellevue,' 'Without a Trace' star Enrique Murciano, who will play a detective alongside Minnie Driver in 'Hail Mary,' and 'Lost' alum Rebecca Mader, who will play a "bitchy" drug rep in 'Work It.'

But tonight on 'CSI' (Thu., 9PM ET on CBS), the 16-year-old singer made his network TV dramatic acting debut -- on a crime series known for its violence and gritty realism.

(S09E10) "It feels like Grissom's last big game. I want to win it for him." -- Nick to Catherine

If you're a fan of closure, if you like solutions and results and answers, here was the episode for you. Grissom's exit gave the writers and producers of CSI a chance to present a show which encompassed most of the elements that characterize what makes this show so popular.

It was sort of a greatest hits episode, if you will, topped with the one scene that kept viewers glued to the set till the end credits. If you missed it by turning away after Grissom's nostalgic stroll through the offices, I'll tell you all about what happened...after the jump.
