"zulu" was filmed in technirama and intended for presentation in super technirama 70, as shown on the prints. in the uk however, the only 70mm screening was a press show prior to release. while the vast majority of cinemas would have played the film in 35mm anyway, the plaza's west end screenings were of the 35mm anamorphic version as well rather than, as might have been expected, a 70mm print. this was due to the uk's film quota regulations, which demanded that cinemas showed 30% british films during the calendar year, but the regulations only applied to 35mm presentations. by 1964 the number of british films available to a cinema like the plaza could be limited and "zulu" gave them several weeks of british quota qualification if played in 35mm. in other countries the public did get to see the film in 70mm.
