Tony Warrin is a very successful pianist who can play practically any kind of music, from classical to Boogie-woogie. He has one ambition left, which is to play at Carnegie Hall. Although his manager, Sam Dunne, and secretary, Marion Moore --who secretly loves him—feel Tony's playing has never been better, he decides to go see Zwolinski, the music teacher who made him the musician he is today. There he encounters Linda Curtis, who mistakes him for Zwolinski and explains why she wishes to learn the piano. In a whirlwind courtship, Tony takes out Linda socially and also performs on the piano for her. He proposes marriage, but since they just met, Linda asks for more time. Before a concert appearance in San Francisco she makes the acquaintance of Howard Ferguson, a soldier who has just returned home and intends to resume his career as a composer. A concert date at Carnegie Hall is finally arranged, only to have tragedy befall Tony—a sudden loss of hearing. It is explained to him that an operation could either cure him or leave him totally deaf. Shaken by this turn of events, Tony turns reclusive and even suicidal inside his New York City penthouse. He learns lip-reading and begins to observe strangers in Central Park, including a young boy, Alvie, who also needs an operation. The boy helps persuade Tony to take a risk, so he undergoes surgery and his hearing returns. He also spies Linda through binoculars with Howard and realizes they are in love, but Linda has been staying with Tony out of sympathy for his situation. Tony plays a Carnegie Hall concert and gives the couple his blessing. When he sees the loyal Marion, he realizes that they can have a future together.
At the time, Liberace was at the height of his career when tapped by Warner Bros. for his first starring motion picture. In April 1955, Modern Screen magazine claimed Doris Day had been most often mentioned as Liberace’s leading lady, "but it is doubtful that Doris will play the role. Liberace’s name alone will pack theatres and generous Liberace would like to give a newcomer a break." Joanne Dru, an established movie actress, became the leading lady.
Release and reception
When the film was released, the studio mounted an ad and poster campaign with Liberace’s name in huge, eccentric, building-block letters above and much larger than the title. "Fabulously yours in his first starring motion picture!" was a tag line. The other players and staff were smallish at the bottom. The film opened at the Paramount Theatre in New York City on November 2, 1955 with appearances by Liberace but performed disappointingly for the rest of the week only grossing $38,000. It closed the following week after just 13 days. The film was a commercial failure since Liberace proved unable to translate his eccentric on-stage persona to that of a movie leading man. Warner quickly issued a pressbook ad supplement with new "Starring" billing below the title, in equal plain letters: "Liberace, Joanne Dru, Dorothy Malone". TCM's Robert Osborne recalls a more dramatic demotion: When Sincerely Yours played first run at the Orpheum in Seattle, the billing was altered even more: Joanne Dru, Dorothy Malone, and Alex Nicol above the title and below the title in much smaller letters: "with Liberace at the piano". Originally, Sincerely Yours was meant to be the first of a two-picture movie contract but the studio then bought back the contract, effectively paying Liberace not to make a second movie. The experience left Liberace so shaken that he largely abandoned his movie aspirations.
