Nevertheless, Kline was hired to play the protagonist, as Reitman considered him to have a presidential look and be an actor "who was both dramatically strong and was light on his feet," as Kline would not only be playing a double role but the film was a comedy that dealt with very serious subject matter. Reitman then called Sigourney Weaver, with whom he had worked in "Ghostbusters", for the First Lady role. Ross was present for production, as he was interested in starting a directing career as well.
