中视在1993~1994年播出的美国影集《时空怪客》(Quantum Leap)是NBC于1989年至1993年间播映的科幻电视影集,描述史考特巴库拉(Scott Bakula)饰演的山缪贝奇特博士(Dr. Samuel Beckett),一个才华洋溢的理论科学家,突然发现自己无法自控地在时空中跳跃,暂时地跟各式各样的人交换身分,出现在后者生命中的某个时刻(多为20世纪的后半部),或是某个重大事件发生时。Doctor Sam Beckett led a group of top scientists into the desert to research his theory that a man could time travel within his own lifetime. Unfortunately, in order to save his funding, he was forced to enter the accelerator prematurely and vanished. He then found himself in someone else's body with partial amnesia. His only contact from home is Al, a holographic image only he can see and hear. Setting right things which once went wrong, Sam leaps from life to life, hoping each time that this is the final leap home.
