Earlier this week, Hero Complex hosted a very special screening of Indiana Jones and the Raiders of the Lost Ark in Los Angeles and AICN was there--catching up with .Steven Spielberg and Harrison Ford.
Spielberg is keen on doing Indiana Jones 5, as is Ford but he was quick to add "I ain’t gonna go to Mars" ala Indiana Jones and the Kingdom of the Crystal Skull
In terms of Indy on Blu-ray, Spielberg says the "Indiana Jones" films are coming "soon" and he would like them out faster but he's waiting on George Lucas.
In fact the Blu for "E.T.: The Extra-Terrestrial" would likely come out before that AND it would only be the original 1982 version, not the altered 2002 re-release since Spielberg has expressed regret over having altered the film and has no such plans to do any more tinkering with any of his past films.
