Apollo 13 is a 1995 American docudrama film directed by Ron Howard and starring Tom Hanks, Kevin Bacon, Bill Paxton, Gary Sinise, Ed Harris and Kathleen Quinlan. The screenplay by William Broyles Jr. and Al Reinert dramatizes the aborted 1970 Apollo 13 lunar mission and is an adaptation of the 1994 book Lost Moon: The Perilous Voyage of Apollo 13, by astronaut Jim Lovell and Jeffrey Kluger.

The film tells the story of astronauts Lovell, Jack Swigert, and Fred Haise aboard the ill-fated Apollo 13 for the United States' fifth crewed mission to the Moon, which was intended to be the third to land. En route, an on-board explosion deprives their spacecraft of much of its oxygen supply and electrical power, which forces NASA's flight controllers to abandon the Moon landing and improvise scientific and mechanical solutions to get the three astronauts to Earth safely. Howard went to great lengths to create a technically accurate movie, employing NASA's assistance in astronaut and flight-controller training for his cast and obtaining permission to film scenes aboard a reduced-gravity aircraft for realistic depiction of the weightlessness experienced by the astronauts in space.
