Catwoman (Tim Burton)

A Catwoman spin-off was announced. Michelle Pfeiffer was to reprise her role, with the character not to appear in Forever because of her own spin-off. Burton was the director, Denise Di Novi and Daniel Waters returned. In 1994, Burton was unsure of his plans to direct Catwoman. Waters joked, "Turning it in the day Batman Forever opened may not have been my best logistical move, in that it's the celebration of the fun-for-the-whole-family Batman. Catwoman is definitely not a fun-for-the-whole-family script." The film labored in development hell for years, with Pfeiffer replaced by Ashley Judd.
