A “Game of Thrones” movie is reportedly in the works. It comes after a year of box office hits and misses for Warner Bros. Discovery.

Matthias Frey, the head of the Department of Media, Culture and Creative Industries at City, University of London, told Business Insider that a “Game of Thrones” film is a “no-brainer.”

“‘Game of Thrones’ had one of the most loyal and passionate fan bases of any media franchise for the last 20 years,” he said. “In addition, it attracted a broader mass audience of non-fantasy fans who were intrigued by its secondary genres or simply wanted those ‘water cooler’ moments of being able to discuss what everybody else was watching.”

Shawn Robbins, director of analytics for movies at ticketing company Fandango and the founder of insights firm Box Office Theory, agreed that a “Game of Thrones” film would be a success. He pointed to the season four finale episodes that were released in US theaters for a week in 2015. They grossed $1.8 million at the box office, according to Box Office Mojo.

“A big screen iteration would be the perfect fit for a fictional universe with such scale, intrigue, and drama,” Robbins said. “There’s tremendous opportunity in bringing this IP to the biggest canvas possible as moviegoers increasingly gravitate toward event-level content.”

The “Game of Thrones” news comes amid a difficult year for Warner Bros. Discovery.

A “Harry Potter” TV series reboot was announced last year after the box office failure of the “Fantastic Beasts” spin-off series. Denis Villeneuve’s “Dune” and Matt Reeves’ “The Batman” universe have also jumped to the small screen with “Dune: Prophecy” and “The Penguin.”

Frey said franchises that extend across different media are popular in the industry right now.

“The name of the game in today’s media landscape is to create transmedia story worlds and cross-pollinate brands across a variety of media formats in order to create a monetization pipeline,” he said.

“Warner Bros. Discovery’s decision to produce a ‘Games of Thrones’ film is part of its strategy to double down on reliable IP in an age of ongoing change and disruption in the media industries,” he added.
