Foyle's War (2002)

Casualties of War - S5-E2

Factual error: The naval captain in this episode has a military mustache as prescribed by army regulations. The Royal Navy regulations, however, prohibited separate mustaches and beards - if facial hair was worn, a "full set" of beard and mustache with the beard joined to the mustache was mandatory, and that to be grown to the commanding officer's satisfaction within six weeks.

DCS Christopher Foyle: The uniform suits you.
Andrew Foyle: Thanks. I wish I could say the same about your dressing gown.

Among the Few - S2-E2

Trivia: The fuel station features metal miniblinds in several scenes. These did not become available until the early 1940s and would aluminium be diverted from airplane production to blinds?

Sunflower - S8-E3

Question: If head of MI5 gave Foyle the file on Strasser at the start of episode, why, when American officer comes to the office for first time, why does he say to Miss Pierce that he didn't know about Stasser?
