Steven Spielberg has been talking to Starlog magazine about what exactly the situation is with a possible "Indiana Jones 4". According to the mag, the "A.I.: Artificial Intelligence" director said that he is ready to make "Indiana Jones 4," but Paramount Studios is holding him and George Lucas back for reasons not given. Apparently, as soon as Lucas gets things worked out then Spielberg will join the project. Still sounds like timing is a factor in all this. Paramount is probably looking to secure a timeslot first, in which Spielberg, Lucas & Harrison Ford would be able to team-up, before they move on with the project.
