Daniel Craig insists 'Spectre' won't be his last James Bond movie.

Although the 47-year-old actor previously hinted that he was ready to quit the franchise after the upcoming movie, he has now insisted that he will make at least one more.

He told Event magazine: ''It's getting harder. But such is life. I'll keep going as long as I'm physically able.

''I'm contracted for one more - but I'm not going to make predictions.

''These movies don't get made very often. It's just the fourth time for me, a spit in the ocean. If you don't get excited about making a movie of this size with this cast, with Sam Mendes... then go home.''

And while Daniel has done less stunt work on 'Spectre' than previous movies, he admitted he still has to work hard to get in shape to play Bond.

He said: ''I'm doing less [stunt work, I've got so many good doubles [but] I work myself to death to get fit.''

Daniel's assertion that he will be back for another James Bond movie comes just one month after he seemed to indicate 'Spectre' was his last.

When asked if he would be back, he told Esquire: ''I don't know. I really don't know. Honestly. I'm not trying to be coy. At the moment I can't even conceive it.

''At this moment, no. I have a life and I've got to get on with it a bit. But we'll see.''
