FIRST OFF . . .

Forget about that ABC-planned TV movie about Donna Rice and former presidential hopeful Gary Hart. It officially bit the dust Monday, according to Hart’s attorney and a network spokesman. The official reason: that perennially pesky Hollywood disease, creative differences, both sides said. However, the one-time model and bit-part actress reportedly balked on providing intimate details of her relationship with the former Colorado senator, which is just what ABC vice president Ted Harbert had said the production would supply when he announced the deal earlier this year.
