In theaters in England and Australia it was titled Blind Terror, and for U.S. it was always See No Evil.
The movies at the theatre, 'Rapist Cult' and 'The Convent Murders', are fictional creations.
Based on the film's conceit of showing the killer solely in close-up from the legs down, his identity is concealed by having all possible suspects filmed only from the waist up in all medium and long shots.
Many of the scenes, including the opening views of the railway station, were filmed in Wokingham, Berkshire.
Sarah (Mia Farrow) talks about her plan to train as a physiotherapist. See No Evil/Blind Terror's writer Brian Clemens later used a training center for the blind that taught physiotherapy as the setting for his story The Eyes Have It (1973).
