A short distance from the west of the Square, on the south side of Panton Street, is the Odeon Panton Street. The Prince Charles Cinema, to the north of the square opened in 1962 with a "satellite dish" design where the audience looks upwards to the stage. The cinema became known for showing pornographic and erotic films during the 1970s, including "Emmanuelle" (1974). It later became a favourite venue for showing cult films, including "The Rocky Horror Picture Show" (1975) and a sing-along version of "The Sound of Music" (1965), and marathon performances including all seven Muppet films back to back. Prices are considerably cheaper than the main cinemas in the square; in 2013 a ticket for a new release at the Prince Charles cost £10, compared to £24 at the Odeon.
