"I think it's based on her being female and the actual rescue."
I think it's based on her being a white, blonde American female and the movie will be based on whatever Hollywood thinks it will take to make the greatest box office proceeds.
I predict that Cameron Diaz will play Lynch and that the Screen Actros Guild will use actual DNA to clone John Wayne as a "father figure" sargeant in time for the filming. Wayne will take the naive and vixen Lynch under his wing during some spectacular espionage shenanigans and exploits behind the enemy lines.
Of course he ultimately sacrifices his life to save hers at a crucial juncture near the movies end but only after the duo have stumbled upon a yound hotshot but shotdown fighterpilot named Brigidair Colonel Voss, played by Ben Affleck. Voss, the F16 Viper "driver", found in the baking dessert, dragging his planes canopy behind him, is single handedly wreaking havoc on the whole Iraqi army that is pursuing him as he struggles heroicly to make his way back to friendly lines. All the while suffering from scorpion bites and the onset of brain cancer too!
However, in spite of his infirmities Lynch falls helplessly head over bootheals in love with him - no small part of that due to his tales of unmatched prowess and superior ability for derring doo.
The high point of the movie will be this; as Voss lays hiding under a cargo tarp mumbling "They can't see me! They can't see me. I'm invisible!!" and John Waynes slowly closes his eyes for the last time again, whispering that Lynch is the son he never had, Lynch will drag herself along the ground for several yards, inspite of a broken leg and more grime than makup, over to an RPG that just happens to be there, loaded, primed and ready to go! Just as the whole Iraqi army cautiously encircles her, guns drawn and mumbling a symian dialect of Arabic, Lynch quickly flips over onto her back and fires the RPG right into Saddam Hussein, killing him with a spectacularly meaty explosion and winning the war.
