Following the relative success of Batman: Mask of the Phantasm (1993), a second film was ordered by Warner Bros. That film was Batman & Mr. Freeze: SubZero, which was made to tie-in with Joel Schumacher's Batman & Robin (1997), but delayed a year when that film received a poor reception. The last Batman direct-to-video film to use cel animation, SubZero was released on March 17, 1998.
