1993 film by Gary Ross
Dave is a 1993 American political comedy film directed by Ivan Reitman, written by Gary Ross, and starring Kevin Kline and Sigourney Weaver. Frank Langella, Kevin Dunn, Laura Linney, Ving Rhames, Charles Grodin, and Ben Kingsley appear in supporting roles. Kline plays a dual role: a presidential lookalike is hired by the Secret Service to be a stand-in for the U.S. president, but the stand-in becomes stuck in the role indefinitely after the president suffers a major stroke that his corrupt White House Chief of Staff (Langella) wants to keep secret from the First Lady (Weaver) and the general public. Dave was released by Warner Bros. on May 7, 1993, and was a box office success by grossing $92 million against a $28 million budget, and was met with critical acclaim.
