Older OSS 117 Films
- Keep Circulating the Tapes: OSS 117 Is Not Dead cannot be found on physical home video supports. There's an upload on YouTube.
- The Other Darrin: Regarding the 1960s Gaumont film series, Frederick Stafford replaced Kerwin Matthews for OSS 117: Mission to Tokyo. Then Stafford was not available to film OSS 117 - Double Agent due to being busy on Alfred Hitchcock's Topaz, so he was replaced by John Gavin.
Jean Dujardin Films
- California Doubling: No scene of OSS 117: Cairo, Nest of Spies was filmed in Egypt. The movie was mostly shot in Morocco.
- Fake Nationality:
- Argentinian-born and French-raised actress Bérénice Bejo as the Egyptian Larmina in Cairo Nest of Spies.
- French actress Louise Monot as the Israeli (of Russian descent) Dolorès Koulechov in OSS 117: Lost in Rio.
- Faux Fluency: In the Cairo Nest of Spies scene in which 117 sings an Arabic cover of "Bambino", Jean Dujardin had to phonetically learn the lyrics.
