Complete series cast summary:


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. Written by Kevin <>

Did You Know?


Sam leapt beyond his date of birth four times. In Quantum Leap: The Leap Back - June 15, 1945 (1991), Al and Sam traded places, due to an accident, which allowed for leaping within Al's life. In Quantum Leap: The Leap Between the States - September 20, 1862 (1993), it was revealed that Sam's great-grandfather had a very similar genetic profile and blood type. In Quantum Leap: Play It Again, Seymour - April 14, 1953 (1989) and Quantum Leap: The Americanization of Machiko - August 4, 1953 (1989), he hadn't been born yet, but had already been conceived. Since he was able to leap into his great-grandfather, that would already allow him to leap outside of his own lifetime. See more »


Ziggy's opening narration says that "only Sam can see and hear" Al which was thought to be true for the first season and for the first twelve seasons of season 2, but Sam and Al discover in Quantum Leap: Another Mother - September 30, 1981 that animals, very young children, the mentally disabled, and people near death can also see and hear him (as well as seeing Sam's true form).

"Oooh Boy!"
28 August 2004 | by See all my reviews

A highly imaginative idea from Donald P. Bellisario.

The selection of Scott Bakula and Dean Stockwell to play the roles of Sam (the quantum leaper) and Al (Sam's advice-giving & holographic guide) was spot on.

The story lines were great. The series consisted mainly of fictional plots, interspersed with the odd story based on real life events. In addition, the show's original signature tune was great!

The acting, especially from Scott and Dean, was first class. In fact, you don't need to be a sci-fi buff to enjoy Quantum Leap ........ a Bellisario masterpiece!

________ 9 out of 10! ________
