18 Again! is a 1988 American fantasy-comedy film directed by Paul Flaherty and starring George Burns and Charlie Schlatter. The plot involves a college student switching souls with his grandfather by means of an accident. The film is based on the song "I Wish I Was Eighteen Again" written by Sonny Throckmorton and recorded by Burns in 1979.

George Burns was an American comedian, actor, writer, and singer, and one of the few entertainers whose career successfully spanned vaudeville, radio, film and television. His arched eyebrow and cigar-smoke punctuation became familiar trademarks for over three-quarters of a century. He and his wife Gracie Allen appeared on radio, television and film as the comedy duo Burns and Allen.
