This is what we found on Wikipedia regarding the Disney's The Lion King (UK):

The Lion King is a 1994 American animated musical coming-of-age drama film directed by Roger Allers and Rob Minkoff, produced by Don Hahn, and written by Irene Mecchi, Jonathan Roberts, and Linda Woolverton. Produced by Walt Disney Feature Animation and released by Buena Vista Pictures Distribution under Walt Disney Pictures, the film features an ensemble voice cast consisting of Matthew Broderick, James Earl Jones, Jeremy Irons, Jonathan Taylor Thomas, Moira Kelly, Niketa Calame, Nathan Lane, Ernie Sabella, Whoopi Goldberg, Cheech Marin, Rowan Atkinson, and Robert Guillaume. The film follows a young lion, Simba, who flees his kingdom when his father, King Mufasa, is murdered by his uncle, Scar. After growing up in exile, Simba returns home to confront his uncle and reclaim his throne.

The Lion King was conceived during conversations among various Disney executives, to whom several writers submitted early treatments. Original director George Scribner had envisioned The Lion King as a nature documentary-style film, with Allers joining as co-director after having worked in the story departments of several successful animated Disney films. Considered to be Disney's first original animated film, The Lion King's plot draws inspiration from several sources, notably William Shakespeare's play Hamlet. Woolverton, screenwriter for Disney's Beauty and the Beast (1991), drafted early versions of The Lion King's script, which Mecchi and Roberts were hired to revise once Woolverton left to prioritize other projects. Scribner departed due to disagreements over the studio's decision to reimagine the film as a musical, with original songs by Elton John and Tim Rice, and Minkoff was hired to replace him in April 1992. Throughout production, the creative team visited Kenya for research and inspiration.

Released on June 15, 1994, The Lion King was praised by critics for its music, story, themes, and animation. With an initial worldwide gross of $763 million, it completed its theatrical run as the highest-grossing film of 1994 and the second-highest-grossing film of all time, behind Jurassic Park (1993). It held the title of highest-grossing animated film until it was replaced by Finding Nemo in 2003. The film remains the highest-grossing traditionally animated film of all time, as well as the best-selling film on home video, having sold over 55 million copies worldwide. It won two Academy Awards, as well as the Golden Globe Award for Best Motion Picture – Musical or Comedy. It is considered by many to be among the greatest animated films ever made.

The success of the film launched a multibillion-dollar franchise comprising a Broadway adaptation, two direct-to-video follow-ups, two television series, and a photorealistic remake (which itself spawned a prequel), which in 2019 also became the highest-grossing animated film at the time of its release. In 2016, The Lion King was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
