Did You Know?

Lesley-Anne Down was cast as Olga by mistake. Blake Edwards meant to audition Nicola Pagett, who played Elizabeth Bellamy on Upstairs, Downstairs, but instead auditioned Ms. Down, who played Georgia Worsley on later episodes of that same series. Julie Andrews commented that she didn't look like the actress in the series, but Edwards wrote it off to lighting and make-up.

First film of Deep Roy.

Blake Edwards's original cut ran 124 minutes, and was submitted to the British Board of Film Censors in 1976. Afterward, the film was cut to 103 minutes. That version was shown in cinemas, on VHS, and on DVD. Most of the scenes cut involved Sellers journey to, and arrival in, in England. The 124 min original cut has never surfaced, but a large chunk of the deleted footage forms the basis of Sellers' scenes in Trail of the Pink Panther. The scenes include: _Peter Sellers in the car on the way to the airport, Sellers on a plane to England (excerpts can be seen in the trailer), Sellers meeting the English police at the airport, and an extended version of the existing scene of Sellers going into his apartment near the beginning of the film, with rice flying everywhere.

The deleted scenes involving Harvey Korman's character "Balls" ended up in the film Trail of the Pink Panther, which was made after Peter Sellers' death.
