- Actor Allusion:
- Michiel Huisman played a guy called Ellis in World War Z too.
- Harrison Ford's character has the last name Jones. And in Indiana Jones and the Last Crusade he and his father fell for the same woman. It's the other way around here.
- Ellen Burstyn played a daughter who became an old woman while her parent remained young in Interstellar too.
- Awesome, Dear Boy: Lee Toland Kreeger found Anthony Ingruber online doing a Harrison Ford impression on YouTube and, upon hearing that he's also an actor, called him up to ask him "how would you like to play your idol and make out with Blake Lively?" Some fans have called for him to star as a young Indiana Jones and Han Solo in future films. Unfortunately, its an unwritten rule in Hollywood that you "never cast an imitator," so it will most likely never happen.
- Billing Displacement: Harrison Ford is second billed and does not appear until an hour into the film. Both Michiel Huisman and Ellen Burstyn feature far more in the film than he does.
- The Danza: Kathy Baker as Kathy Jones.
- Doing It for the Art: Lee Toland Kreeger shot some of the flashback scenes on film, and had to send them down to California to be processed - as there was nowhere in Canada to process film - just to achieve the Retraux look.
- Fake American: Michiel Huisman is Dutch playing the American Ellis. Anthony Ingruber is Canadian playing the American William's younger self.
- Hide Your Pregnancy: Blake Lively was two months pregnant by the time they finished filming, so she had to do very little to hide it.
- Playing Against Type: Blake Lively is usually some form of Ms. Fanservice or Everyone Loves Blondes. Here she plays a lonely and withdrawn Woobie who can never grow older and must watch her friends and loved ones die.
- Separated-at-Birth Casting: Anthony Ingruber was cast precisely because he looked like such a young Harrison Ford. He even managed to fool people into thinking Ford dubbed his voice. He's just that good as a soundalike.
- What Could Have Been: The movie was originally greenlit as a Katherine Heigl vehicle back in 2010, with Angela Lansbury as Flemming. Natalie Portman was also offered the lead role but turned it down.
