Oscar winner "Game of Thrones" fans everywhere. When the actor was given the chance to embarrass his "Early Man" co-star Maisie Wiliams during "The Radio 1 Breakfast Show" on BBC Radio 1, he opted instead to try to get her to spill Season 8 spoilers.

As a guest on the show, Williams had agreed to participate in their Heart Rate Monitor Challenge, meaning host Nick Grimshaw got to interview her while she sat in a hospital bed, attached to -- you guessed it -- a heart rate monitor. Grimshaw then did his best to fluster Williams, enlisting the help of her boyfriend, Ollie Jackson, and her flatmate and "iBoy" co-star, Bill Milner. Their contributions both led Williams to share hilarious misadventures, but the real treat came at the end.

Grimshaw brought in Redmayne and asked the actor if he knew any "horrible stories" that would sent Williams's pulse racing. Redmayne immediately declined to take that track and took a much better one.

"I don't know about the horrible stories, because I thought, well, basically, it's just about 'Game of Thrones' spoilers," he said, making the day of all "Game of Thrones" fans listening.

Redmayne then jumped right into it, hypothesizing that Williams's character, Arya Stark, will end up leading the Seven Kingdoms. He and Grimshaw did their best to analyze the actress's response, but to be honest, they weren't able to glean much from her changing heart rate. We did like Redmayne's creativity, though -- particularly when he suggested that Arya and Hot Pie (Ben Hawkey) will "get it on, become a thing, have kids, the full works."

Watch below; Redmayne's joins around the 6:18-mark.

"Game of Thrones" Season 8 premieres in 2019, while "Early Man" hits theaters Feb. 16.
