First full length feature film directed by Sidney Hayers.
The circus used in this movie was that of Billy Smart's Circus, one of the three big tenting circuses in the United Kingdom at the time of filming. The external scenes were filmed on Clapham Common.
The footage of the trapeze act featured in the film (complete with inter-cuts of audience reaction) is identical to that in 'John Moxey''s 'Circus of Fear (1966)'
The song "Look for a Star", used throughout the film during the circus sequences, became a hit pop recording in Great Britain (for Garry Mills) and the United States (for the similarly named Garry Miles). It was written by the young Tony Hatch under his regular pseudonym of Mark Anthony.
