Walters appeared in the West End in the 1942 naval play Escort by Patrick Hastings and the 1949 musical Her Excellency at the London Hippodrome.

[7] Walters' television appearances included the Granada series Crown Court, both as a judge and as a barrister.

He also appeared as a barrister in the BBC Series A P Herbert's Misleading Cases, starring Roy Dotrice as Albert Haddock.

In the DVD commentary to The Man Who Haunted Himself, actor Roger Moore mentioned that co-star Walters lived in Dolphin Square in Pimlico, London in which some scenes of the film were shot.

That visit resulted in the Terry-Thomas Gala held in the Theatre Royal, Drury Lane in the same year which raised funds to help Thomas live the rest of his life in comfort.
