Jeannie Epper had at least 100 screen roles, maybe even 150 — no one is quite sure. But because she was a stunt double, galloping on horseback, crashing cars and kicking down doors for the stars of films and television shows, hers was not a household name. In her heyday, however, Ms. Epper was ubiquitous. She hurtled through the air most weeks as Lynda Carter’s stunt double on the hit television series “Wonder Woman” and mimed Ms. Carter’s leggy lope. Ms. Epper, whose bruising career spanned 70 years, died on Sunday at her home in Simi Valley, Calif. She was 83.
