Did you know that famous Hollywood director Michael Curtiz (Manó Kaminer), who directed classics such as The Adventures of Robin Hood (1938), Casablanca (1942) and many many more, served as an Austro-Hungarian soldier in the First World War?

"The intoxicating joy of life was interrupted, the world had gone mad", Curtiz wrote of the war in 1960, "We were taught to kill ... [M]any things happened: destruction, thousands forever silenced, crippled or sent to anonymous graves."

Interestingly, many of the cast of Casablanca had served during the First World War on opposite sides. Humphrey Bogart in the US Navy, Claude Rains in the British army on the Western Front and Conrad Veidt in the German Army in the Eastern Front.

Peter Lorre, who was originally from Hungary and who's Real name was László Löwenstein, was too young to serve himself, but his father, Alajos, was a lieutenant in the Austro-Hungarian army and served on the Eastern Front in 1914-15 and was later put on charge of a POW camp.
