I Believe in You is a 1952 British drama film directed by Michael Relph and Basil Dearden, starring Celia Johnson and Cecil Parker[2] and is based on the book Court Circular by Sewell Stokes.

The ingredients combine sentiment, comedy and some artificial melodrama in casily assimilated proportions, the manner is episodic, the technique has the smooth, journalistic proficiency that one expects from Basil Dearden – continually on the move, never penetrating far beneath the surface of a situation.

Through the office pass eccentric old women (including that familiar figure, the elderly lunatic who thinks that the neighbours are poisoning her cat), drunks, delinquents, the reformable and the hard cases.

Cecil Parker turns from a bumbling do-gooder into a hard-nosed champion of the underprivileged as he helps Harry Fowler and Joan Collins to stumble back on to the straight and narrow.

"[7] The New York Times wrote, "it shines with understanding and, except for a brash climactic moment, it is a warm and adult adventure, which pins deserving medals on unsung heroes without heroics.
