Kit Harington is clearly drawn to dark, brooding characters.

Winter is Coming reports that Harington, who is best known for his role as Jon Snow in the hard-hitting HBO series Game of Thrones, spoke on a panel at ACE Comic Con this past weekend. Though he was there to discuss his upcoming role as Dane Whitman, a.k.a. Black Knight, in the upcoming Marvel Studios film The Eternals, his involvement in—and love for—other franchises came up during the conversation.

The moderator of the panel surprised the audience by bringing up Harington’s love for the Harry Potter series, and, of course, asked him which Hogwarts house he aligns with. The 32-year-old actor responded, “I am a Gryffindor. I’ve thought very deeply about it.” Though Harington himself identifies with the lion-hearted, he does believe that Jon Snow would be a Hufflepuff because of his undying loyalty.

Harington was then asked which character he would want to play in a hypothetical Harry Potter prequel movie about the Marauders—a group of Gryffindors that included James Potter (Harry’s dad), Sirius Black, Remus Lupin, and Peter Pettigrew, who attended Hogwarts a generation before Harry and his friends. And who were often at odds with Slytherin Severus Snape.

Harington's response was immediate, and enthusiastic:

Severus Snape is the most tragic, wonderful, brilliant [character] ... He’s a character you hate, and then end up loving. He’s just phenomenal. I don’t think I’m right for him, so I’ll play Sirius. But, whoever gets to play Snape, that’s a great character.”
