Indiana Jones is losing it's eldest member.
Sean Connery announced he's 'out' of the series and wants to spend more time studying for Celebrity Jeopardy. Connery is currently retired and declined on the movie role as Indy's dad.
Loosely translated, Lucas couldn't come up with enough "$" to make his retirement sound boring. Pity! But, we don't really blame him. Hell of an actor. Let him do what he wants. The good news is that Harrison Ford is now old enough to play the part of old geezer in the film.
