Demi Moore, the star of “Disclosure” and “Indecent Proposal” and 1995 NATO Female Star of the Year, is wrapping a deal for Castle Rock Entertainment’s “Strip Tease” for what sources say is an unprecedented upfront fee for an actress. Insiders peg it at around $10 million to $12 million.

“Strip Tease” is a Lobell/Bergman production based on the novel by Carl Hiaasen. Mike Lobell is producing the project to be released by Sony Pictures. Andrew Bergman, who directs, also adapted for the screen. The partnership, which dates back to 1981’s “So Fine,” more recently produced “The Freshman,” “Honeymoon in Vegas” and “It Could Happen to You.”

The film’s budget could expand further if Jack Nicholson becomes available for the key male role of a corrupt politician. The two performers previously worked together on Castle Rock’s “A Few Good Men.”

The darkly ironic tale centers on a woman who takes a job in a South Florida strip club to raise money in her fight to regain custody of her young daughter. Lensing is scheduled to begin in September.

The word at Castle Rock is that basic deal points have been agreed upon with Moore, but several other financial details in her contract are yet to be completed.
