I was only thinking about the real story in Bourne Legacy by Eric Von Lustbader if they are adapting that novel. In that book, Jason Bourne is an older person and the Antagonist is (I think if I remember correctly) his own lost/kidnapped son, named Khan another assassin, who is equally lethal as Jason himself. So a good plot, but it failed to touch people like Robert Ludlum used to.

If they adapt Bourne Ultimatum in the real format, then both Jason Bourne and Carlos are old men in that as well. So, Matt Damon would need a lot of make up to look 60, just as Carlos would (Maybe Clive Owen can do that)

It would be a bomb combination. They should have talked Matt Damon into it. It would be nowhere close to what his trilogy did as business.

The only actor that might sound a bit like the younger Jason Bourne might be Jake Gyllenhall.
(I like him too, he is Bourne like)

But after Matt Damon has played Bourne very recently and three times, it is a hardball for any new Actor to beat that talented man.

I was watching Goodwill Hunting and also followed up with Informant, both flicks were on HBO and great movies. This was last week. What a wonderful opportunity for Gilroy. But Damon said, he won't work w/o Greengrass I gathered.

I saw Green Zone, not a bad flick at all, but I guess Americans are bored of war movies specially about Iraq. If it portrays some intense story about the Victims and the cries of women, children and old folks in the war torn areas, then it might be an instant hit, but the trouble is, it would portray the Americans as villains in such stories. So nobody risks writing up such Screenplays.

The reality of all this is "It starts from a Madame Madelaine Albright"

Tony Gilroy Explains How Bourne 4 Was Created Without Bourne


The fourth Bourne installment took a seeming step backward when it was announced that writer-director Tony Gilroy's (Michael Clayton) script wouldn't include the character of Jason Bourne (Matt Damon). Gilroy, who helped write all three of the previous Bourne movies, was tasked by Universal with writing Bourne 4 in June. Then, when The Bourne Supremacy and The Bourne Ultimatum director Paul Greengrass decided he wouldn't return for a fourth, the studio hired Gilroy to direct.

But why no Bourne in Bourne 4? For one, once Greengrass bowed out, Damon countered, saying he "wouldn't do [another Bourne] with anyone" other than Greengrass. This left Gilroy the opportunity to expand the Bourne mythology, though Gilroy admitted to Deadline that when he met with the estate for Bourne author Robert Ludlum back in the spring, he told them he had no ideas for a fourth Bourne.


I thought --  this is a bad move. Se the problems here:


Tony Gilroy is a great Screenwriter and a Story writer, maybe he is really the only genius here, but he won't deliver a successful 4th Bourne w/o Matt Damon and Paul Greengrass. They established a CERTAIN kind of pace and action genre elements in the three movies already made -- although all of those three were far away from the actual books by Ludlum. Another issue, in my humble opinion is "Eric Van Lustbader" He is definitely a great writer, but not in the same mould as Ludlum. I have seen the Bourne Identity (Original Teleplay, Richard Chamberlain-Jaclyn Smith, directed by Roger Young) at least 30 times, to learn about how the dialogues in movies are written, or in a teleplay either. Lustbader wrote this Bourne book titled "The Bourne Legacy" it is terrible in some parts. I couldn't read it fully, because I started to feel "This writer has gone nuts, he doesn't understand the real WIRING of Jason Bourne aka David Webb, from Ludlum's books" I think, Universal will rue this idea, because people internationally would want Damon-Greengrass combo. Let us wait and watch. This should be an interesting thing to think of the 4th Bourne movie. Jeremy Renner is a great action hero, so all good luck to him to "Try and top Matt Damon's performances in the Bourne Trilogy"

Anyway, good luck Gilroy, too!.

Ciao.
