Paula Valenska receives an 'and introducing' credit. However, this was her seventh film, and it marked her British debut.
Jean Cadell is often credited wrongly with being in this film. The BFI holds the contracts for this project (Robert Lennard special Collection); she did not sign one.
Some sources say Michael Gough is in this film. However, he did not sign a contract; BFI Special Collections has these documents, and his name is not on them.
