Ralph Thomas' 1954 Technicolor comedy film Mad About Men starred Johns alongside actors Donald Sinden and Anne Crawford in this sequel to Miranda. Johns starred as Jo Luton in Roy Boulting's 1955 comedy Josephine and Men, a romantic comedy film in which Jack Buchanan's Uncle Charles Luton examines his niece's relationships, and supported Danny Kaye in the musical-comedy medieval romance costume drama film The Court Jester of the same year, playing Jean with "cunning precision". Despite having the highest budget of any comedy made at the time, The Court Jester was badly received at the box-office. When the episode Doctor's Orders of Star Trek: Enterprise aired in 2004, Johns made a surprise guest appearance when a clip of The Court Jester was shown on screen.
