Production is now under way in Los Angeles on Katherine's new CBS television show Doubt, which is set to debut mid-season.

Doubt is an exciting and unconventional new legal drama about a prestigious boutique New York firm headed by a legal legend (Elliot Gould). The practice attracts top talent looking to prove themselves, including brilliant lawyer Sadie Ellis (Katherine Heigl) who finds herself falling in love with a client — a prominent pediatric surgeon (Steven Pasquale) accused of a brutal murder committed in his youth.

Cast and crew took to social media to celebrate the first day of principal photography, with Katherine sharing a photo of herself alongside co-stars Dulé Hill and Steven Pasquale:
