Christy Marx, creator of Jem (1985), said she had no idea a film was going to be made, and was upset that Hasbro did not inform her about it. Her lack of involvement was not permanent however, and she was given a cameo role in the film as the Rolling Stone editor Lindsey Pierce.
Following a disappointing opening weekend of only $1.3 million, the worst opening ever for a major studio film in wide release (2,000+ theaters), Universal pulled the film after only two weeks, giving it one of the shortest theatricals runs ever. Before it was withdrawn, it had grossed just $2.2 million against an estimated budget of $5 million.
Jem's original voice actors, Samantha Newark and Britta Phillips (singing voice), make cameo appearances in the film, as a hairstylist and stage manager respectively.
When the film was originally announced, it was planned as an animation, but later, the decision was made to shoot it as a live-action film.
