Men in Black (stylized as MIB: Men in Black) is a 1997 American science fiction action comedy film[2] based on the comic series of a similar name by Marvel Comics. The film was directed by Barry Sonnenfeld, written by Ed Solomon, and is the first installment in the Men in Black franchise. It stars Tommy Lee Jones, Will Smith, Linda Fiorentino, Vincent D'Onofrio, and Rip Torn. In the film, Kevin Brown / Agent K (Jones) and James Darrell Edwards III / Agent J (Smith) investigate a series of seemingly unrelated criminal incidents related to the extraterrestrial lifeforms which live in secret on Earth.

Development for the film began in 1992, after producers Walter F. Parkes and Laurie MacDonald optioned the rights to the comic book series. Solomon was soon hired to write the screenplay; Sonnenfeld was the preferred directorial choice, which resulted in delays due to his commitments to other film projects and failure to secure any alternative directors. Principal photography began in March 1996 and lasted until that June, with filming primarily taking place in New York City. Produced by Columbia Pictures and Amblin Entertainment, the film's visual effects were helmed by Industrial Light & Magic. The film's soundtrack contained the theme song of the same name, performed by Smith.

Men in Black premiered at Pacific's Cinerama Dome in Hollywood on June 25, 1997, and was theatrically released in the United States by Sony Pictures Releasing on July 2. It received critical acclaim for its screenplay, action sequences, and the performances and chemistry of Jones and Smith. The film grossed over $589.4 million worldwide, becoming the third-highest-grossing film of 1997 and the ninth-highest-grossing film of the decade. It won for Best Makeup and was also nominated for Best Art Direction and Best Original Score at the 70th Academy Awards, among numerous other accolades. The sequel, Men in Black II, was released in 2002.
