In those days there was a thing called "barring", which meant that no other cinema within a specified area could show the film. The two chains, ABC and Rank (mainly Odeons but also still some Gaumonts and other odds and sods), had "alignments" with distributors which meant that if you wanted to see, e.g., a Warner Bros. film you had to go to the ABC and if you wanted to see a 20th Century Fox film you had to go to the Odeon. By the 1980's closures had reduced the number of cinemas so that some places only had one left, which still had to give preference to its aligned distributor. Most of the survivors had been tripled, which often meant that the old circle became screen one with 600 to 800 seats, while the rear stalls were divided into two "minis" with around 120 to 150 seats. Very often a cinema had to play its aligned distributor's film in the big screen while a more popular film from the other chain was relegated to a mini.
