The battle of the sexes is alive and well in Hollywood, and whether it is the subject of a rom-com or an indie flick, audiences love to watch a good ol' fashioned throw down. But what makes a 'battle of the sexes' comedy a tricky proposition is that someone has to lose. So how do you make your audience (who is for the most part, female) accept the idea that a strong and feisty gal has learned the error of her ways and has 'surrendered to love''? Granted, it was a heck of a lot easier when they were making these movies in the '30s and '40s and marriage was the inevitable 'happy ending' for most gals.

Today, The Ugly Truth has been released on DVD and just like a million films to go before it, the story centers on a man and a woman who 'meet cute', fight a lot, and then fall in love -- and just like every other film, the whole thing hinges on the happy couple. When you're covering well trod ground like a battle of the sexes comedy, the charm and likability of your leads are your bread and butter -- and on a personal note, I just don't think Truth pulled it off, and I never got that charge from watching Katherine Heigl and Gerard Butler engage in a little 'verbal foreplay'.

So at risk of sounding like somebody's grandmother, I decided that when it comes to the battle of the sexes comedy, nobody did it better than classic Hollywood, and it didn't matter whether it was during the hay day of screwball comedies or gritty films noir. That's why this Cinematical Seven is dedicated to those classic Hollywood couples that could battle with the best of them, but unlike Heigl and Butler, their chemistry became the stuff of movie legend.
