Two ITV Studios Dramas Land on SHOWTIME & Paramount+

SHOWTIME has acquired two thrillers from ITV Studios: Quay St Productions’ The Guest and SISTER’s Coldwater.

The Guest bows on October 17 for Paramount+ premium plan subscribers in the U.S. before its on-air launch on October 19 on Paramount+ with SHOWTIME. Remaining episodes will premiere weekly. Coldwater will launch in 2026.

“I am so pleased that these gripping shows have found such a strong U.S. partner in SHOWTIME,” said Tom Clark, executive VP of global sales and commercial strategy at ITV Studios. “When it comes to premium British drama, it really doesn’t get any better than Quay Street and SISTER, so I have no doubt the discerning SHOWTIME audience won’t be able to get enough of either one. Our buyers told us what they wanted: intense, attention-grabbing thrillers, so we set out to find the best and I’m excited for these two incredible titles to begin their global journeys.”
