This is not the most thought-provoking movie of all time, but it doesn't deserve the trash heap either. It's basically the story of a playboy out of control in a sophomoric way that would fit John Ritter to a 'T' in the Three's Company years. But his character Zach has far more substance than that; although that substance is to reach his goal to "screw" everything that moves. He's a playboy and he wants desperately to be on the up and up. But, he can't shake his "nature". Ritter plays the goof at his best and the performances of the supporting cast (Gardenia, Reed, Brooks, Donat) are perfect. Certain scenes beyond the popular glow-in-the-dark scene are priceless. This movie by Blake Edwards looks like "Citizen Kane" compared to "10".
