London Belongs to Me (also known as Dulcimer Street) is a British film released in 1948, directed by Sidney Gilliat, and starring Richard Attenborough and Alastair Sim.

Among them are the landlady, Mrs Vizzard (played by Joyce Carey), who is a widow and a believer in spiritualism; Mr and Mrs Josser (Wylie Watson and Fay Compton), and their teenage daughter Doris (Susan Shaw); the eccentric spiritualist medium Mr Squales (Sim); the colourful Connie Coke (Ivy St. Helier), the young motor mechanic Percy Boon (Attenborough) and his mother (Gladys Henson).

Percy is in love with the Jossers' daughter and turns to crime to raise money to impress her with, but he bungles a car theft and finds himself accused of murder.

With the assistance of Mr Josser's staunchly socialist Uncle Henry (Stephen Murray), they gather thousands of signatures on a petition to win him a reprieve.

The Monthly Film Bulletin wrote, "Norman Collins' story, which is Dickensian in the richness of its pathos and kindly humour, has been triumphantly captured on the screen.
