Trivia / Quantum Leap S 4 E 22 A Leap For Lisa

• Acting for Two: Variation: You can clearly tell that, in the scenes in the Imaging Chamber where Al talks with Bingo, they have overdubbed Bingo's actor with Dean Stockwell's voice, with some minor pitch shifting.
• Casting Gag: When Al is erased from the timeline, Dean Stockwell is replaced by Roddy McDowall. They replaced one renowned former child star whose career continued strong into adulthood with another. Some bonus points should also be awarded to the fact that Dean and Roddy had been friends for decades.
• You Look Familiar:
  • Charles Rocket (Commander Riker) previously appeared as Michael Blake in Season 3’s A Little Miracle.
  • Rich Whiteside (Marine Guard) was Doc in "The Leap Home, Part 2: Vietnam".
