Jennifer Tilly stars as Ginger Quail, an adult film star, in this black comedy. Her character acts as the primary obsession and romantic catalyst for the main character, setting off a wild cross-country trip. The people the encounter on that adventure include the ever-odd Crispin Glover and our ubiquitous main man, Eric Roberts.
Jennifer used the Carol Wayne formula as her path to showbiz success:

As I’ve noted in the past, there are simply mysteries in the human experience that can’t be explained. This is just one of them, like the suffering of innocent children, the existence of an afterlife, and the popularity of James Corden.
