'The Undoing' Beats 'Game of Thrones' to Become Sky's Biggest U.S. Series Launch

The opening episode of HBO's limited series reached a cumulative 28-day audience of 3 million.

Nicole Kidman and Hugh Grant have won an unlikely battle against the forces of Westeros, at least in terms of ratings from across the Atlantic.

The opening episode of HBO's glossy limited series The Undoing has reached a cumulative 28-day audience of more than 2.78 million viewers for Comcast's European pay-TV giant Sky, making it bigger than the launch of Game of Thrones on Sky in 2011.

With the first three episodes attracting an audience of more than 2.5 million, Sky has now said that the David E. Kelley-created psychological drama — due to reach its finale on the network Nov. 30 — is now on track to become the biggest U.S. series to ever launch on its Sky Atlantic channel. It has already surpassed recent U.S. shows includes Watchmen, True Detective and Big Little Lies.

While The Undoing enjoyed solid ratings on HBO in the U.S., where it launched on par with recent releases such as Lovecraft County, it appears to have celebrated greater success overseas. It had the best first first season premier of 2020 for HBO's networks in the Nordics and Central Europe, and was the best first season launch of all time for HBO in Denmark.

Directed by Susanne Bier, The Undoing follows Grace Fraser (Kidman) as she is forced to question her entire life in the aftermath of a violent death, a missing husband (Grant) and a suspicious affair.
