Woody Allen believes that he's yet to make a "great" film.
The filmmaker, who has a record 14 writing nominations at the Academy Awards, has just enjoyed his biggest hit in decades with Midnight In Paris.
But Woody, 76, said: "I'm still trying to make a great film, and that goal keeps me going. To keep trying to make something that I feel could play alongside films that I consider great."
The Annie Hall and Hannah And Her Sisters director said: "If there was a festival... and they were showing 12 films, and they were showing Citizen Kane and The Bicycle Thief, that I could have one of mine in there with it, and they would say, 'Oh, yeah, that's one of the 12'."
Woody, whose next film is the ensemble comedy Nero Fiddled, starring Penelope Cruz, Woody himself and Alec Baldwin, said he could see himself working long into the future.
"If my health holds out and if people want to keep financing my films, why not?" he said.
"It's not rocket science. I mean, it's not such a Herculean task. You're talking about a film a year. That's like saying to a cab driver, 'You want to do 10 fares a year?' I'm not doing a film a month or some ridiculous thing.
"We're also pampered in showbusiness... Guys work these enormous schedules - lawyers, teachers, doctors, they work around the clock all year long. In show business, what is it to do a film? It sounds like a lot, but it isn't."
He added: "If you have something to say and a good idea, the age is irrelevant. If I saw myself, cut to me in my 90s and I'm making these films that drone on and nobody sees them and they're utterly irrelevant to everybody, that's pointless.
"But if I make a film and it entertains people and they like it? If I made Midnight In Paris - I mean, there's no reason I couldn't make that same film, if I had the health, 20 years from now."
