Kit Harrington spoke to Access Hollywood's Sibley Scoles at Marvel's "Eternals" premiere red carpet and the new dad opened up about how he's feeling being away from his 9-month-old son. "I miss him, it’s the first time I’ve been away from him for more than a few days…I’ve been cooped up with him for a while." Kit and his "Game of Thrones" costar Rose Leslie welcomed their baby boy in February. "Eternals" is out in theaters on Nov. 5.
