Ncuti Gatwa was cast as the 14th incarnation of “Doctor Who.”

Most fans just found out about the news last Sunday.

However, the “Sex Education” actor has known for a while.

He told the BBC that he’s known since February of this year.

He joked, “it's been tricky trying keep this under wraps, because I've got a very big mouth.”

However, he said that “It feels amazing, it feels really amazing.”

Gatwa continued, “this role is an institution, and is so iconic.”

Gatwa said that he’s going to “do my own thing” and not channel any previous reincarnations.

“I mean they're all amazing,” he said. “You can't pick. You cannot pick.”
