Tania Raymonde

The Chicago Fire spin-off is taking shape.

Tania Raymonde and Scott Eastwood are the first actors to be cast on the as-yet-unnamed spin-off about the Chicago Police Department, which will air as Chicago Fire's Season 1 finale on May 15, TVLine.com reports.

Is NBC planning a Chicago Fire spin-off?

Raymonde, 25, who played Ben's doomed daughter Alex on Lost, will play an officer identified thus far only as Nicole. Eastwood, actor-director Clint Eastwood's 27-year-old son who has appeared in his dad's films Invictus and Gran Torino, will play a cop named Jim Barnes.

Chicago Fire executive producer Dick Wolf is obviously no stranger to spin-offs, having launched Law & Order spin-offs Law & Order: SVU, Law & Order: Criminal Intent, and the short-lived Law & Order: Trial by Jury and Law & Order: Los Angeles.
