Actor Harrison Ford has said he feels "fit" at the age of 64 to reprise the role of action hero Indiana Jones.
Harrison Ford first took on the role of Indiana Jones 25 years ago
Ford, who last played the part in 1989's The Last Crusade, said he could "bring the same physical action" to a fourth movie.
George Lucas and Steven Spielberg have said they are working on a script for the fourth movie, which has been in development for more than 10 years.
Ford said that Sean Connery may return as Indiana Jones' father.
"He's part of the emotional fabric of these films. I believe that Sean is still willing and I'd be delighted if he joined us," said the actor at the Rome Film Festival.
Former James Bond star Connery, who was at the Rome event last week, said that no offer had been made.
Ford did not disclose any further details about a possible filming schedule or locations, adding that Lucas and Spielberg - who worked on the previous films - have yet to complete a script.
"I think it's a real opportunity to make a film as successful as the ones we've made before," he said.
The first two films in the Indiana Jones trilogy were Raiders of The Lost Ark (1981) and 1984's Temple of Doom.
The trilogy picked up a total of seven Academy Award nominations, while Steven Spielberg gained a best director nomination for Raiders of The Lost Ark.
