Brook believed the film was never released because it “wasn’t regarded as very good”.

Another critic Matt Robinson, who also previewed the film, wrote: “This is not only a good film it is educational too.
“A good document of history that many journalists and non-journalists will enjoy.”
Oz was first published in Sydney, Australia, in 1963 and its first UK publication was in 1967.
