Julie Andrews filmed a cameo role as a maid removing the unconscious Clouseau from Claudine's room, but her part was edited out.
Milton Reid is credited as Japanese Restaurant Owner, but he is nowhere to be seen in the film.
Missing Episode: Until June 2017, no boxset of the film series included this film, due to Universal owning the distribution rights at the time. They were all available, but Shout! Factory's release of all the Sellers films marks the first time they've been together, as apparently MGM was able to get the full US distribution rights to the film back from Universal within the past couple years, whereas before, they only held digital distribution rights. Universal still holds UK distribution rights, however, with a UK Blu-ray licensed to and released by British label Fabulous Films.
