Amanda Peet didn’t think husband David Benioff’s idea to co-create Game of Thrones was such a great idea for a television show.

Amanda Peet‘s husband proved her wrong with his highly successful HBO series.

During an appearance on the Late, Late Show With Conan O’Brien, the 43-year-old actress conceded to the funny host that initially she thought the idea was not all that great.

“Yes, I thought it was a terrible idea. Terrible! Just silly. Like Dungeons & Dragons, but real, with real people,” she told Conan, which was greeted by boos from the audience.

“Now I’m obsessed!” Amanda Peet reassured the perplexed and angry audience.

Game of Thrones, which premiered in 2011, is based on a series of book by George R.R. Martin, A Song of Ice and Fire . The show, which is an obsession for so many fans, will return for a fifth season in April.
