"I remember watching Armageddon as a child. In one scene they were walking on the asteroid and there was fire in the open. I remember pointing out to my dad that ”fire can’t exist in space!”. Perhaps I was just a nerdy kid."
REPLY: "I however have no issues with drillers being trained as astronauts. But yes, I heard a story that NASA grads watch Armageddon and have to spot as many physics errors as they can."
"In pretty much any zombie movie, when people run to an elevator to get away from the zombies the doors always seem to close on the zombies trying to get in. They never pop back open like they would if someone actually stuck their hand (or any other limb/ object) in the way of the doors. I haven’t watched it in a while but in the (newer) Dawn of the Dead I’m pretty sure it happens."
REPLY: "This is because zombies do not have souls. As the Simpsons proves in “Bart Sells His Soul” the automatic doors at the Quik-E-Mart does not work on Bart when he doesn’t have his soul, I would imagine the same applies to zombies and elevator doors."

"In the original 1990 Teenage Mutant Ninja Turtles film, you can see the actor inside Donatello’s costume."
"Back to the Future. DeLorean backwards after crashing into barn. Not glaringly obvious but in 1955 Marty plays a guitar that won’t come out until 1958"
"Sonny’s “punch” to his brother-in-law, in The Godfather. Missed by a mile."
"The Fast and the Furious, the line “Granny shifting, not double clutching like you should” Why the hell would you double clutch during a drag race? Just proved the writers had no clue about cars, much less racing them."
REPLY: "There’s a scene in the fifth(?) one where he is in reverse and he shifts into another gear in reverse. lol"
