Tom Selleck played architect Peter Mitchell in the 1987 film Three Men and a Baby.
The comedy centers on three unmarried roommates in New York who unexpectedly become responsible for an infant. Selleck’s Peter is one of the three men, alongside Michael, played by Steve Guttenberg, and Jack, played by Ted Danson. Their improvised caregiving gradually changes their understanding of responsibility and family life.
The film was directed by Leonard Nimoy and is an American remake of the French film Trois hommes et un couffin. It became a major box-office success and was the highest-grossing film in the United States in 1987.
The film is sometimes remembered as a straightforward fatherhood story, but the three men are not initially the baby’s legal parents. Its title refers to the unusual caregiving situation that forces them into parental roles.
