Director Sam Mendes has just recently finished a reported 128-day shoot for his second entry in the James Bond franchise, "Spectre." In a new interview with the BBC, the filmmaker reveals this is likely his last go-around with 007.

"I said no to the last one and then ended up doing it, and was pilloried by all my friends," Mendes, who also helmed "Skyfall," said. "But I do think this is probably it. I don't think I could go down that road again. You do have to put everything else on hold."

Mendes went on to say that he thoroughly enjoyed filming the two Bond films, the most recent of which comes out on October 26 in London and November 6 in the U.S. However, it's the large commitment that each film requires that's squashed any desire to do a third.

"It feels almost, even though we've just finished shooting it, like one big experience and it was a fantastic life-changing thing," he said. Still, because the films are "pretty much all encompassing," with the two he's done taking a total of five years to make, he doesn't think he'd go back. "It really is more a lifestyle choice than a job," he added.

He also said that the theme song for "Spectre" had been recorded, but he refused to let slip the name of the performer. "I can say that the song's been recorded and it's fantastic and I'm very excited about it," he said. "You won't have to wait long."

Mendes directed a stage production of "Charlie and the Chocolate Factory" between his Bond films, and will likely return to theater again once "Spectre" finally comes together. "I'm happiest rehearsing a play or editing a movie, and when I've finished editing a movie I generally want to be back in a theatre environment again," he explained. "It feels like home, it feels controllable after the chaos of a movie set. But it won't be long before I want to do another film, and I'm very fortunate to be able to go back and forth between the two."
