Harrison Ford, 71, was airlifted to Wexham Park Hospital in Oxford after sustaining a broken ankle when a falling door hit him on the set of Star Wars: Episode VII at Pinewood Studios. The incident happened on Thursday.

He underwent several tests and x-rays after he was seen holding his chest in pain. The extent of his injuries is still unknown. A statement from Disney said that they will be resuming filming his scenes once Ford has fully recuperated. Producers of the film are saying that Ford could miss up to eight weeks of filming.

“At the moment it looks like Harrison is going to be off set for 6-8 weeks but the main priority is making sure he is OK,” the source said.

A source from the set said that they had a hard time moving things around after the accident. “We can juggle things, bring some scenes forward and push others back. There are lots of other actors in the movie so it is not a disaster. We are still confident the film can stay on schedule.” The bosses are working on rescheduling shooting schedules for the movie, so that they can continue filming while Ford recuperates.

Ford’s wife, Calista Flockhart, flew from the U.S. to be by her husband’s side.

Reports said that the Health and Safety Executives are now investigating how the accident occurred. They are looking to see whether there has been any breach of legislation. Some are saying that Ford was hit by the door of the Millennium Falcon, which is a spacecraft that is commanded by Ford’s character Han Solo.

This is not the first time Ford sustained an injury while filming. In 1983, he sustained a herniated disc to his back while filming Indiana Jones and the Temple of Doom. He also sustained a torn ligament to his knee on the first Indiana Jones movie.
