In the now classic Halloween film Hocus Pocus, the action centered around an enchanted cat named Binx who was actually a boy named Thackery Binx who had a curse placed upon him.
The role of Thackery Binx was credited to two actors because one actor played the character while another provided the voice. Sean Murray, an actor who would find fame a decade later on CBS' long running crime drama NCIS as Timothy McGee would act as Thackery Binx when he is in his human form.
Thackery's voice was provided by Jason Marsden, both in cat and human form. Jason would go on to quite a career with Disney, finding roles on Boy Meets World and becoming the voice of Goofy's son Max. He continues to have a successful career providing voices to characters on many cartoon shows.
