Finance was obtained from Nat Cohen at EMI Films - they provided the entire budget. The poster was designed by John Troke, a publicist who had introduced Box to the book of "Doctor in the House" 15 years earlier. A script was prepared by Hugh Leonard while Thomas and Box filmed "Doctor in Trouble". The film was shot at Elstree Studios and on location in London. The film's sets were designed by the art director Robert Jones. Ray Davies of the The Kinks wrote the film's soundtrack "Percy".
