Indiana Jones and the Kingdom of the Crystal Skull producer Frank Marshall has revealed details on the film.

Talking to Empire magazine, the producer said that the film was currently in the editing process and that John Williams was working on the film's score.

Marshall claimed that the fourth film will remain true to the series and retain similar features of the previous instalments.

"I would say that we're completely in the style and the tone of the first three movies," he said.

"We have all the iconic elements we had in the first three. I would say it's closest to the third one. It's all adults."

George Lucas recently revealed that the film would be set in 1957 and would pay tribute to low grade science fiction films.

Harrison Ford's character will be joined this time round by a new sidekick, believed to his estranged son Mutt.

On Indiana's new assistant, played by Shia LaBeouf, Marshall said: "He brings a youthful arrogance that Indy can play off of and there's a lot of banter between the two of them."

Cate Blanchett will play an evil Russian agent named Spalko and Karen Allen returns as the love interest from the Raiders of the Lost Ark film, Marion Ravenwood.

Ray Winstone will also feature as a rival archaeologist.

"He's a friend and a foe of Indiana Jones, they've known each other over the years," Marshall stated.

"They came together in the past and now they are coming together again. There's a rivalry but also a friendly rivalry."

The film will be released globally on May 22nd.

The March issue of Empire goes on sale on February 1st.
