At a heavy steel security gate, the two burly security staffers posted at a private club's entrance step out of the shadows to check credentials. After verifying the guests identity, they open a heavy steel security gate and wave the car ahead. As it rounds a copse of trees, the passangers can see for the first time the large mansion house ahead. The renovated estate, once the home of a famous movie star in the 1920's, is now an exclusive club where celebrities can watch or participate in challenge catfights.

Jack Nicholson and Warren Beatty were the masterminds behind the concept. They had the clout, financial resources and, most importantly, the interest of fellow celebs necessary to make their dream a reality. Catty women weren't hard to find in their profession. Over the years, Hollywood had broken many an actresses heart on a near daily basis and intense competition for roles and recognition guaranteed there'd always be bad blood between many of the beautiful women in the business.

Nicholson and Beatty were long time buddies; friends who shared a common passion: catfighting. They searched for and then bought this expansive estate. After several years of planning, renovation (and greasing palms of city officials) their dream finally came to fruition.

The concept was simple: membership was restricted to celebrities approved by the owners, security being paramount to prevent outsider's from penetrating the club's property. Memberships had started slowly, but after several matches word got out and current membership numbered well over a hundred. There was a large lounge on the ground floor of the club, with a "battle room" in the basement. Women who wanted to issue a challenge entered their ID number on a computer keyboard behind the bar, followed by the name of the woman they were challenging. Sometimes both celebs were in attendance at the time of a challenge, but more often the woman challenged was out of town on location shooting a film or on perhaps on tour promoting a current release. If she didn't check in at the club within a week, she was privately notified of the challenge. If she accepted, a mutually agreeable date for the fight was set.

The battle room could seat 50 people comfortably around a 20 by 20 foot mat. Rarely were there any more spectator's since celebrities schedules and other commitments prevented it. The battles were pure catfights - no rules, no time limit - a fight to the finish. Medical personnel were on hand in case of injury and they were usually kept busy. The fact that female celebs would actually participate didn't surprise the owners in the least; indeed, they'd both witnessed several epic catspats in their long careers. The concept for a club was brilliant; a fantasy transformed into reality and all the catfight enthusiasts in Hollywood, both male and female, came running; eager to join and to participate!

It was Jack Nicholson who came up with the name for the new club:
