Mac and Me II

A sequel for the film Mac & Me was planned (and hinted at the end of the film). However, it was quickly scrapped due to the failure of the first film.

Why It Was Cancelled

 * 1) The first film was a critical and commercial failure mainly due to it being considered a ripoff of E.T.
 * 2) The stars of the first film quit after it failed at the box office meaning if a sequel was to be produced, new actors would have to be hired.

Results

 * The sequel was permanently cancelled.
 * Mac and Me is a stand-alone film.
