Oliver Platt has been tapped to co-star in NBC’s Chicago Fire planted spinoff, Chicago Med. Platt is joining S. Epatha Merkerson, Yaya DaCosta and Laurie Holden in the ensemble medical drama project whose cast will be introduced in Episode 19 of Chicago Fire this season. Platt will play the intelligent head of psychiatry, Dr. Daniel Charles.

The Chicago Med planted spinoff is being conceived and written by Dick Wolf, whose company Wolf Films produces the Chicago Fire/Chicago PD franchise, and the franchise’s Matt Olmstead, Derek Haas and Michael Brandt. The Universal TV-produced project reunites Platt with Wolf and NBC after toplining the 2000 series Deadline.

In the past several years, The West Wing alum Platt has largely stayed on the cable side with stints on The Big C and Fargo. He will next be seen in an arc on CBS’ The Good Wife. In features, Platt, repped by WME, is finishing the untitled Howard Hughes film for Warren Beatty and will appear in Miramax’s 9th Life Of Louis Drax.
