Question: What language is Jeannie speaking at first and how do they get around the three wish rule?
Answer: As noted elsewhere here Jeannie is speaking Farsi.
Answer: Regarding the three wishes, there was never any set-in-stone rule or belief. This appears to originate from "The Ridiculous Wishes" or "The Three Ridiculous Wishes" that is a French literary fairy tale written by Charles Perrault and was published in 1697. It sort of set the standard for genie rules that later appeared in other folk tales and then in movies and TV shows. Like vampire lore, common details can be changed by any author to suit their story.
Answer: She's speaking Persian. And there was never a 3 wish rule. When Tony freed her, he became her master, and she'd do anything for him (i.e. grant his every wish).
Answer: The core POWs regularly escaped the prison camp but they made it their mission to conduct espionage and commit sabotage in the surrounding German territory. They also collaborated with different underground resistance groups and used a network of secret tunnels to help prisoners from other POW camps to escape, who then relayed vital information back to the Allied forces. Hogan and his men maintained the illusion that Stalag 13 had never had any prisoners escape in order to avoid their covert operations being shut down. Being that the prison camp is set in Germany during WWII, there were no American embassies.
