The Return of the Pink Panther is a 1975 comedy film and the fourth film in The Pink Panther series. The film stars Peter Sellers returning to the role of Inspector Clouseau for the first time since A Shot in the Dark (1964), after having declined to reprise the role in Inspector Clouseau (1968). The film was a commercial hit and revived the previously dormant series and with it Peter Sellers' career. Herbert Lom reprises his role as Chief Inspector Charles Dreyfus from A Shot in the Dark. Also reprising their roles from the previous film are André Maranne as François and Burt Kwouk as Cato; the three thereafter became regulars in the series. The character of Sir Charles Litton is played by Christopher Plummer. David Niven, who played the part in The Pink Panther (1963), was unavailable. The stolen Pink Panther diamond once again plays a central role in the plot. Plot In the fictional country of Lugash, a mysterious thief seizes the Pink Panther diamond and leaves a white glove embroidered with a gold "P".

Clouseau has been temporarily demoted to beat cop by his boss, Chief Inspector Charles Dreyfus (Herbert Lom), who despises him to the point of obsession, but the French government forces Dreyfus to reinstate him.

Upon examining the crime scene in the national museum — in which, due to his habitual clumsiness, he wrecks several priceless antiques — Clouseau concludes that the glove implicates Sir Charles Litton (Christopher Plummer), alias "the notorious Phantom," as the thief. After several catastrophic failures to stake out Litton Manor in Nice, Clouseau believes a mysterious assassin is attempting to kill him. He follows Sir Charles' wife, Lady Claudine Litton (Catherine Schell), to the Gstaad Palace hotel in Switzerland in search of clues to her husband's whereabouts, and repeatedly bungles the investigation. Meanwhile, Sir Charles is teased about the theft by his wife, and realizes he has been framed. Arriving in Lugash to
