1973, he appeared in a Benson & Hedges cinema commercial; in 1975, he appeared in a series of advertisements for Trans World Airlines, in which he played several eccentric characters, including Thrifty McTravel, Jeremy "Piggy" Peak Thyme and an Italian singer, Vito. Biographer Michael Starr asserts that Sellers showed enthusiasm towards these roles, although the airline campaign failed commercially. A turning point in Sellers's flailing career came in 1974, when he teamed up with Blake Edwards to make The Return of the Pink Panther, starring alongside Christopher Plummer, Herbert Lom and Catherine Schell. The film was shot on a budget of £3 million and earned $33 million at the box office upon release in May 1975, reinvigorating Sellers's career as an A-list film star and restoring his millionaire status. The film earned Sellers a nomination for the Best Actor – Musical or Comedy award at the 33rd Golden Globe Awards. In 1976, he followed it with The Pink Panther Strikes Again. During the filming from February to June 1976, the already fraught relationship between Sellers and Blake Edwards had seriously deteriorated. Edwards says of the actor's mental state at the time of The Pink Panther Strikes Again, "If you went to an asylum and you described the first inmate you saw, that's what Peter had become. He was certifiable." With declining physical health, Sellers could at times be unbearable on set. His behaviour was regarded as unprofessional and childish, and he frequently threw tantrums, often threatening to abandon projects. His difficult behaviour during productions was widely reported and made it more difficult for Sellers to get employment in the industry at a time when he most needed the work. Despite Sellers's deep personal problems, The Pink Panther Strikes Again was well received critically. Vincent Canby of The New York Times said of Sellers in the film, "There is, too, something most winningly seedy about Mr. Sellers' Clouseau, a fellow who, when he attempts to tear off his clothes in the heat of passion, gets tangled up in his necktie, and who, when he masquerades—for reasons never gone into—as Quasimodo, overinflates his hump with helium." Sellers's performance earned him a further nomination at the 34th Golden Globe Awards. In March 1976 Sellers began dating actress Lynne Frederick, whom he married on 18 February 1977. Biographer Roger Lewis documents that of all of Sellers's wives, Frederick was the most poorly treated; Julian
