Mann has composed songs for movies, most notably "Somewhere Out There", co-written with Weil and James Horner, for the 1986 animated movie "An American Tail". Linda Ronstadt and James Ingram performed the song as a duet during the movie's closing credits; their version was released as a single, which scored No. 2 on the Billboards charts and became a "gold"-scoring record. "Somewhere Out There" would win two 1987 Grammy Awards, as Song of the Year and Best Song Written for a Motion Picture or Television. "Somewhere Out There" was also nominated for a 1986 Oscar as best song, but lost to "Take My Breath Away" from "Top Gun" (a film that featured the Weil-penned "You've Lost That Lovin' Feelin'" in a key scene). Mann's other movie work includes the scores for "I Never Sang for My Father" and "Muppet Treasure Island", and songs for "National Lampoon's Christmas Vacation" and "Oliver & Company".
