Spiderman star Toby Maguire has said the latest film in the series - due next year - may not be the last big screen outing for the superhero.
"There will be some conclusions, though I wouldn't say it's necessarily the end," he told fans in California.
At comic book convention Comic-Con in San Diego, California, Maguire said Spider-Man 3 would be left "open-ended".
"If there are stories worth telling, then we'll tell them," he added.
