Upcoming NBC drama Chicago Med has completed its new female cast additions with the hire of Marlyne Barrett (The Wire). The Chicago Fire spinoff producers had said that they would introduce three new female characters in the wake of the departure of original cast member Laurie Holden. That includes Barrett and recently cast Torrey DeVitto and Rachel DiPillo. Barrett will play Maggie, a multi-tasking force of nature, a battle-ax with wit and sass.

The series, from Wolf Films and Universal TV, stars Oliver Platt, S. Epatha Merkerson, Nick Gehlfuss, Yaya DaCosta, Colin Donnell and Brian Tee. Chicago Med, which just underwent a showrunner change, with Andrew Schneider and Diane Frolov replacing Andrew Dettman, premieres Tuesday, November 17.

This marks Barrett’s return to the Dick Wolf fold. She has appeared on three Law & Order series, including arcs on the mothership Law & Order and Law & Order: SVU. Barrett, who appeared on American Crime last season, is repped by Abrams Artists Agency and managed by Lisa Gallant at Gallant Management.
