Archaeologist action hero Indiana Jones will return to the big screen on
22 May 2008, Paramount Pictures has said.
The announcement means the movie will open on Memorial Day weekend in the US, as the previous two Jones films did.
Shooting is due to start in June 2007, with Harrison Ford returning in the whip-cracking title role.
The original Indiana Jones trilogy was a tribute to Saturday morning B-movies, and made more than $1.1bn at the box office in the 1980s.
The fourth instalment had been in development for more than ten years, but creator George Lucas and director Steven Spielberg have now signed off on the script.
Lucas said last month it would be "a character piece" including some "very interesting mysteries".
Ageing hero
The screenplay was written by Jurassic Park and War of The Worlds scribe David Koepp, who told film website IGN it had taken "about a year" to complete.
"You realise this is a beloved character," he said, "and a lot of people are going to be angry no matter what I do".
Koepp also said the movie would acknowledge its hero's advancing years.
Harrison Ford, who last played the Jones role in 1989, is now 64.
Last year he said he would "bring the same physical action" to the new film as he did to the original trilogy.
