Sam Mendes could make another Bond movie following the huge success of his 007 debut Skyfall.
The Oscar-winning American Beauty director has been working on a plot for a follow-up, according to the regular screenwriters of the series.
Neal Purvis and Robert Wade, who have worked on five James Bond films, also revealed they are quitting the franchise.
Speaking during an appearance at the fourth Doha Tribeca Film Festival, Wade said: "We're very happy to have done five Bonds, I think we've gotten it to a good place.
"I know that John Logan (screenwriter) and Sam Mendes have come up with a plot for another one, which takes the pressure off because these films take up a lot of time."
Purvis, who has been writing movie scripts with Wade for 28 years, said: "We were going to stop with Quantum Of Solace, but it's good to go out on a high with Skyfall."
Current 007 Daniel Craig, who has starred in the last three Bond adventures, is contracted for a further two.
Skyfall, which was released last month, became the UK's biggest box office hit of the year in the space of just 12 days.
It is also the most financially successful Bond film ever, having already taken more money than the highly-acclaimed Casino Royale in 2006.
