'Passport to Pimlico' trivia and fun facts

At the start of the film a radio announcement mentions Latin music performed by "Les Norman and his Bethnal Green Bambinos". This is an in-joke referring to Ealing producer Leslie Norman. Bethnal Green was an unattractive area in the East End of London.

The original negatives of this and other Ealing comedies were lost in the Henderson's Film Laboratories fire in 1993.

A placard can be seen that says "Forget that Cripps feeling": this refers to Stafford Cripps, who was at the time Chancellor of the Exchequer.

The part of Prof. Hatton-Jones was written as a man and was offered to some male performers before it was decided to make the role female, and Margaret Rutherford was cast.

The isolation of Pimlico and its support by the common people of London is a reference to the Berlin blockade of June 1948 - May 1949.
