In the wake of Sam Mendes' new James Bond film "Spectre", which has already grossed more than $80 million worldwide, the director has indicated he's likely done with the franchise.

In an in-depth interview on Deadline, Mendes says that "Spectre" will likely be his final Bond film. Mendes states that there was, "A sense of completeness that wasn’t there at the end of 'Skyfall', and that’s what makes this feel different. It feels like there’s a rightness to it, that I have finished a journey."

The speculation surrounding Mendes' finality coincides with the end of the Bond franchise's deal at Sony, which is set to expire after the release of "Spectre". Mendes, who also directed 2012's "Skyfall," said that if neither he nor Daniel Craig return for the next Bond film, that it would be like watching "Doctor Who." "You regenerate, and you have to be as brave as when they cast Daniel, and when they let M die," he told Deadline. "They have to go off in a completely different direction, into regenerating mythology. You cast a new actor and find a new director, and make something totally new."

With "Spectre" in theaters now and the uncertainty of a director, an actor, or even studio producing the next installment, a lot remains unknown for the next Bond film, which will be the 25th in the franchise.
