I've enjoyed reading everybody's predictions. Now that this round is almost over, and with no degree of seriousness, let me just suggest:
At 5'7" and 128 pounds, Honor Blackman doesn't give away much size to Tina Louise, and Honor is the only woman here to actually learn judo. She turns Tina's forward momentum into throws, prevailing in a long battle.
Claudia Cardinale is a future champion, and her size and temper are a challenge for Esther Williams, whose "38" C-cups always included a couple inches of padding. But the older athlete has just enough to prevail in a fight that takes a lot out of her.
Brigitte Bardot is too agile for the stronger Rita Hayworth, whose strategy of trying to bull rush the thinner woman works initially. Brigitte quickly adapts, though, and Rita soon wears herself out. Once she's down, she succumbs to a leg scissors.
As veteran colleagues and friends, Marilyn Monroe and Jane Russell know the studios have too much riding on them to mess each other up. Marilyn submits after some mild wrestling.
Tough Angie Dickinson feels she's not getting any respect from the judges, and turns that bad attitude into a whirlwind attack to upset talented Joi Lansing, who may have taken her too lightly.
With her toned dancer's body, Mitzi Gaynor's strength surprises Jayne Mansfield. When Jayne finally gets on top, she leans forward to try a breast smother, but Mitzi flips her and pins her.
Martha Hyer is fit and strong, and experienced Ava Gardner quickly realizes that grappling with her in a fair fight would leave too much to chance. Ava reaches into her bag of dirty tricks to turn the battle her way. After a forearm shiver leaves Martha bleeding from the nose and mouth, the referee calls the contest.
In the scrappiest match, Gina Lollobridiga and Mamie Van Doren quickly move past slaps to kicks and punches. The free-for-all goes back and forth until Mamie lands awkwardly and twists her knee. Gina shows no mercy toward her hobbled opponent, targeting the injured joint until Mamie submits.
