The Church Mouse is a 1934 British comedy film directed by Monty Banks and starring Laura La Plante, Ian Hunter and Edward Chapman.
A bank owner's prim and uptight Secretary suddenly blossoms during a business trip to Paris.
In 1934 the current head of the bank Jonathan Steele is as technology-obsessed as his predecessors and installs an intercom and constantly flies by plane.
He dismisses a very attractive secretary who is distracting him by trying to seduce him at work, in order that they can become lovers after office hours.
This creates a vacancy which a hard-pressed young woman, Betty Miller, who self-describes herself as a "church mouse", fills by showing Steele how super-efficient she is.
