Harrison Ford

The pair appeared together in Steven Spielberg's 1989 sequel Indiana Jones and the Last Crusade, with Sir Sean playing Ford's father Henry Jones.

"He was my father... not in life... but in Indy III," said Harrison in an interview with Variety.

"God we had fun - if he's in heaven, I hope they have golf courses. Rest in peace, dear friend," he added.

Ford recalled the "pleasure" of taking Sir Sean "for a ride in the sidecar of a Russian motorcycle, bouncing along a bumpy, twisty mountain trail and getting to watch him squirm".

They say Ford, aged 74, was instructed to land on a runway at John Wayne airport in Orange Country on Monday.

But instead he mistakenly landed on a parallel taxiway, passing over a waiting American Airlines plane with 110 passengers and crew on board.

That plane safely departed minutes later. Ford has not commented on the reported incident.

Just before the landing, the Indiana Jones star is quoted as asking air traffic controllers: "Was that airliner meant to be underneath me?"

Steven Spielberg will also be back to direct, having headed up all the previous four films.

"Indiana Jones is one of the greatest heroes in cinematic history, and we can't wait to bring him back to the screen in 2019," said Alan Horn, chairman of The Walt Disney Studios.

"It's rare to have such a perfect combination of director, producers, actor and role, and we couldn't be more excited to embark on this adventure with Harrison and Steven."

Kathleen Kennedy and Frank Marshall will produce the film, which is slated to hit the big screen on July 19, 2019.
