Trivia: Where Eagles Dare
- The Danza: Mary Ure as Mary Elison.
- Dyeing for Your Art: Natural blonde Darren Nesbitt's hair is such an unusual shade because it had to be dyed twice. He was supposed to get it dyed back to blonde from another color (he often appeared with brown or black hair in films). But an accident with the process turned his hair green, forcing them to dye it again, turning it that unnatural-looking shade of platinum blonde.
- So My Kids Can Watch: Specifically written by Alistair MacLean to give his mate Richard Burton a good old-fashioned adventure romp to show the kids (said kids wanted to see their dad in something that wasn't highbrow).
- Viewers Are Morons: According to Darren Nesbitt, when he pointed out to director Brian G. Hutton that he didn't think Nazis had helicopters in World War II, Hutton simply replied, "They won't know that in Arkansas."
