50 free Quantum Leap trivia questions with answers — trivia quiz, new questions added Oct 2026.
Quantum Leap sent a scientist bouncing through recent American history, waking up each week in a stranger's life with a wrong to put right before he could move on. With only a wisecracking hologram for company, Sam Beckett became a boxer, a beauty queen, a lounge singer and dozens of other people, and the show mixed comedy, romance and social drama in a way few series have managed since. This quiz covers the leaps fans remember best, the famous faces who turned up before they were stars, the rules of the time-travel project, the people in Sam and Al's lives, and the stories behind the camera. It includes a few questions on the second-season episode Thou Shalt Not... and on the revival that picked up the story three decades later. It is written for anyone who watched the original run, caught it in reruns or found it through the new series. The early questions are ones most viewers can get, the later ones are for fans who know their episodes, and every answer comes with a short explanation.
