Which 1998 animated film featured Carey's duet 'When You Believe' with Whitney Houston?

The 1998 animated film featuring Mariah Carey's duet “When You Believe” with Whitney Houston was The Prince of Egypt. The song was created for DreamWorks' animated retelling of the Exodus story and appeared in a pop-oriented version over the film's end credits.

Stephen Schwartz wrote the original music and lyrics, while Kenneth “Babyface” Edmonds added material and reshaped the arrangement for the commercial single. In the film's narrative version, the song is associated with Tzipporah and Miriam, voiced by Michelle Pfeiffer and Sally Dworsky. The Houston-Carey recording uses a more radio-friendly pop, soul, and gospel arrangement.

The duet was notable because it brought together two of the biggest vocal stars of the 1990s. Both singers connected with the song's religious themes and its message about hope, perseverance, and miracles. The lyric was revised from “you can do miracles when you believe” to “there can be miracles when you believe,” placing less emphasis on people performing miracles themselves.

The song was released in October 1998 and appeared on The Prince of Egypt soundtrack, Houston's My Love Is Your Love, and Carey's compilation #1's. It is often misidentified as a song from a later animated musical because of its standalone pop success.
