House of the Dragon cast reveals who's the funniest actor on set and no it isn't Matt Smith

Even though House of the Dragon is known for its intense drama, the set is full of laughter, thanks to some hilarious moments among the cast. During a New York Comic Con panel on October 20, actors Matt Smith, Fabien Frankel, and Tom Glynn-Carney shared funny stories about their time filming the fantasy series.

One of the highlights was Rhys Ifans, who plays Otto Hightower. According to the cast, Ifans often lightens the mood on set. Frankel, 30, joked that while Ifans knows exactly what’s going on with his character, he often acts like he has no idea what’s happening. “He’d be like, ‘No idea what’s going on today,’” Frankel said, making the audience laugh.

Smith, 41, who plays Daemon Targaryen, called Ifans “the funniest man on the planet.” Frankel added that working with Ifans can be a real challenge because of how much he makes everyone laugh. “Every day is an uphill struggle to try and do something professional,” Frankel joked.

He even shared how difficult it was for the show’s producers. “I feel like I can feel HBO behind the monitor going, like, ‘Jesus f***ing Christ, Rhys,’” he said, imagining how hard it must be for them to keep everything on track when Ifans is around.

Despite the laughter, Ifans’ character Otto Hightower plays a serious role in the series. According to House of the Dragon co-creator Ryan Condal, Otto will have an important role in the next season. “The Otto Hightower tale has not yet come to an end,” Condal teased in an interview with Variety in August.

House of the Dragon premiered in August 2022 and its second season came out in June 2024. The show is expected to continue for two more seasons, with season 3 set to begin production in 2025.
