Speechless (1994)

Synopsis
A mix of political satire and a modern take on 1930's-style screwball comedy, this romance from director Ron Underwood was assumed by many to be based on the real-life relationship between liberal political consultant James Carville and conservative commentator Mary Matalin. Michael Keaton stars as Kevin, an insomniac who meets Julia (Geena Davis) in a store late one night as they haggle over the last bottle of sleeping pills. After spending a romantic evening together, Kevin and Julia each discover to their chagrin that the other is a rival speechwriter in a nasty New Mexico senatorial campaign. As the senate race heats up, the bickering pair tries to keep the relationship alive, but then Julia's ex-fiance Baghdad Bob Freed (Christopher Reeve), a network news foreign correspondent, shows up with the intention of renewing their relationship. ~ Karl Williams, All Movie Guide
