Dreyfus later escapes from the hospital and again tries to kill Clouseau by planting a bomb while the chief inspector (by periodic arrangement) duels with his manservant Cato.

Although Jarvis is later killed by the kidnappers, to whom he had become a dangerous witness, Clouseau discovers a clue that leads him to the Oktoberfest in Munich, West Germany.

Many nations instruct their operatives to kill Clouseau to gain Dreyfus's favor and possibly the doomsday machine.

As a result of their orders and Clouseau's obliviousness, all of the assassins kill each another until only the agents of the Soviet Union and Egypt remain.

However, their tryst is interrupted first by Clouseau's apparent inability to remove his clothes, and then by Cato's latest surprise attack, which causes all three to be hurled into the river Seine when the reclining bed snaps back upright and crashes through the wall.

As a result, it is the only Pink Panther sequel that has a storyline (Dreyfus in the insane asylum) that directly follows that of the previous film.

The production saw the construction of a full-scale replica of the White House Oval Office at Shepperton Studios, while the Doomsday Machine was designed by engineers from Sony.

The scene in which Clouseau impersonates a dentist who uses laughing gas and extracts the wrong tooth is inspired by Bob Hope's role in The Paleface (1948).

Their tense relationship is noted in Revenge of the Pink Panther's opening credits that list it as a "Sellers-Edwards" production.

French comic-book writer René Goscinny, the original writer of the Asterix series, was reportedly trying to sue Edwards for plagiarism in 1977 after noticing strong similarities to Goscinny's script titled Le maître du monde (The Master of the World), which he had sent to Sellers in 1975.

"[11] Vincent Canby of The New York Times wrote that the characters of Clouseau and Dreyfus "were made for each other," and further stated, "I'm not sure why Mr.

Sellers and Mr. Lom are such a hilarious team, though it may be because each is a fine comic actor with a special talent for portraying the sort of all-consuming, epic self-absorption that makes slapstick farce initially acceptable—instead of alarming—and finally so funny."

Sellers and Mr. Edwards delight in old gags, and part of the joy of The Pink Panther Strikes Again is watching the way they spin out what is essentially a single routine".
