Tom Mison (Sleepy Hollow), Janet Montgomery (New Amsterdam) and Jordan Stephens (Feel Good) have joined the cast of The Ex-Wife, Paramount+'s original UK drama series. They join previously announced series lead Céline Buckens (Showtrial). 
BlackBox Multimedia and Night Train Media have teamed together to develop an adaptation of Jess Ryder's novel The Ex-Wife. The producers are eyeing the adaptation as a TV series, rather than as a one-off. The Ex-Wife follows newlywed Tasha, who has the perfect house, a loving husband and a beautiful little girl. She'd be set if it wasn't for Jen, her husband's ex-wife who just won't leave them alone. Catherine Steadman (Downton Abbey) is penning the adaptation.
