Williams as Suzanne de Passe. The opening titles of the film shows footage of the real Jacksons rehearsing, performing on stage, a few clips from the "Can You Feel It" music video, album covers, magazine covers and pictures of the family. The film is mostly based on the autobiography written by Katherine Jackson, who issued the 1990 autobiography, My Family. Part one of the film was based on how Joseph and Katherine managed to raise their children, first in Gary, Indiana, then later dealing with The Jackson 5's early fame and its consequences. Part two of the film is based on the struggles of young Michael Jackson as he deals with his brothers marrying early into The Jackson 5 success, his problems with acne as a teenager, his eventual solo superstardom based on the success of his albums Off the Wall and Thriller and his legendary Motown 25 performance of "Billie Jean" as well as his difficult relationship with his father.Michael Jackson’s voice is heard on: “Beat It,” “Human Nature,” “Billie Jean,” “I Want You Back,” "I Wanna Be Where You Are," “I'll Be There,” “Rockin' Robin,” “ABC,” and “Dancing Machine.” On all other songs, the Michael Jackson vocal part is performed by Anthony Harrell, Jason Weaver or Kipp Lennon.
