A 1969 BBC television documentary, "Return to the River Kwai", made by former POW John Coast, sought to highlight the real history behind the film (partly through getting ex-POWs to question its factual basis, for example Dr Hugh de Wardener and Lt-Col Alfred Knights), which angered many former POWs. The documentary itself was described by one newspaper reviewer when it was shown on Boxing Day 1974 ("The Bridge on the River Kwai" had been shown on BBC1 on Christmas Day 1974) as "Following the movie, this is a rerun of the antidote."
