Rob Cohen is lying though his teeth and i can prove it because he himself said in his blog that he never met or talked to Rachel and that she left the series after the Mummy returns. So why would Rachel's agent call him about the sons age in the film if she was not apart of the film in the first place?

Here is the link that contradicts his comments in Entertainment Weekly:

"A few of you have inquired about Rachel Weisz and this deserves a response. Rachel decided to leave the franchise many years ago, after "The Mummy 2" finished shooting. We all had hopes that she would change her mind but I never had the opportunity to meet her or talk to her."

What you are hearing is sour grapes from a director who is trying to get publicity for his film by bashing an actress who left the production because she did not like the script, a script that has been bash in certain circles by those who have read it.

This link not only reviews the script but has an insider in the production of Mummy 3 that explains why Rachel left the film.

"Kudos to Rachel Weisz for jumping ship on this ancient turd in the making, really well done. So while the official word has been that her schedule would not allow her to return to the third film, sources close to actress have said that the script was the real reason why she did not come back"

And here are more sources that confirmed Rachel leaving because of the script

Mum's the Word?
Remember those fun Mummy movies with Brendan Fraser and Rachel Weisz? The first installment was happening, the second one not so much, but both made some pretty big bank. Enough so that Universal was hopin' to squeeze a third flick out of the franchise.
"Course, there's been talk of this Egyptian redo stuff for some time. First, it was reported early last year that both Brendan and Rach wouldn't reprise their roles. Then there were mouthings in September that B.F. had signed back on. And now I'm hearing there are more back-'n'-forth machinations regarding the mummified redo attempts.
Rachel Weisz
According to inside busybody beetles on the project, both stars are on the verge of walking off from discussions...but for different reasons. The Oscar-winning Rach is reportedly less than thrilled with the script.
"It's basically a very bad repeat of the first two films but without the charm or wit," say loose-lipped insiders unafraid of big-studio voodoo curses for blabbers.
And I'm told Brendan - ”on the other cash-siphoning hand - ”wants a bigger paycheck and more back-end profits than Universal is willing to offer.

And here are more that confirmed that story:

5 months is a looong time

Good one Fred!!! We always want to believe the worst don't we? Plus I don't think she would care about playing a 21 year olds mom. Angelina did it and was still sexy - and Charlize Theron certainly pushes the envelope of playing 'out of character' characters and she is still hot stuff too. That guy is a jerk.

please do a fashion find I love the shift dress with that red belt

Sorry Amy but my post alone proves you're wrong.

I loved The Mummy and was excited about the The Mummy Returns. However, the sequel was a STINKER!! It was awful and if I were Rachel, I'd have dropped out after that dud as well. I'd have been more shocked if she had agreed to be in this one.

In her new yet-to-be-released movie "The lovely Bones" she is playing the mother of two teenage daughers, one who is murdered, the other who grows into her twenties in the film....So...Yeah, she would play the mother of a 21 year old.....

There's no drama here. She chose not to do a sequel. Whatever her reasons.
