I disagree.
First, having a Bond girl return in a Bond movie is like having a Bond girl return in a Bond movie. Having Marion return in an INDIANA JONES movie would be like having Marion return in an INDIANA JONES. Indiana Jones is NOT James Bond. Flash Gordon stuck with Dale Arden through every series, and it didn't diminish his character. Tarzan had Jane, etc.
1. The relationship has to go somewhere! Oh no, that would be character development. This is bad for movies why? Add to which I don't think it was horrible to have Leia move more into an action role in JEDI, after the supporting role she played in the previous two films. I think there are places for women in action movies, outside the LARA CROFT genre. I don't think they need to be expendable.
2. Yes she would be a sidekick, or secondary character, and Jones would do most of the real work. This is precedented, and frankly welcome. Disappearing her and turning Jones into James Bond (look at his white tux and questionable values (money over preservation of the artifact) in TEMPLE OF DOOM) was just standard paint-by-numbers stuff. Keeping her around would have had the effect of creating a different kind of action series from everything else out there. "She would be a sidekick" is not an argument that she NEEDS to go.
By your argument in a sequel to TRUE LIES, Arnold would have to have divorced Jamie Lee Curtis, since their relationship problems were resolved. Now he needs a new bitch. (No, really, that IS your argument!!!)
3. The romances in the other JONES movies are terrible like all the romances in every James Bond film. This is your weakest point.
4. I guess it was cheaper to hire Sean Connery to liven up the series? I personally would have jumped at the chance to see Marion in the third film, more than Indy's dad, and I'm sure she was cheaper. Anyway, the price of actors shouldn't figure in your personal assessment of whether the characters are good or not. Let the producers worry about that.
5. Not at all:
http://imdb.com/gall...,%20Karen%20(I)Incidentally, she's making a new movie right now in Ladner, a crappy little suburb of my hometown of Vancouver. It's a small role (literally); she's practically retired to doing smaller parts since having a child.
6. This I agree with, sure. All the same, the time to write her out was after the Ark was found, not casually between films. Leaving the two together, moving her to Aerica with him, made it look like she was someone in his life now. The return of RAIDERS characters was a lot of what was fun about THE LAST CRUSADE, and they didn't detract near as much as that awful romance (trivia: the love interest from CRUSADE turned down the role of Eowyn because she didn't want to live away from home for that long .... ). I would have loved to have had Marion a part of the cast reunion.
Bottom line: Karen Allen wasn't in the Indy sequel because Karen Allen didn't want to be in it. She turned it down after the miserable experience of being bitten by all those snakes in RAIDERS. So it was actually a business decision, and not a storywriting necessity after all, to write her out.
