My One and Only is a 2009 comedy-drama film loosely based on a story about George Hamilton's early life on the road with his mother and brother, featuring anecdotes that Hamilton had told to producer Robert Kosberg and Merv Griffin. Kosberg pitched the idea of this true story to screenwriter Charlie Peters, then Merv Griffin shepherded the project from screenplay to production, until his death in 2007. Merv Griffin's company served as one the film's producers and Robert Kosberg executive produced.
In New York City in 1953, Anne Deveraux lives with her bandleader husband Danny, their 15-year-old son George, and Anne's somewhat older effeminate son Robbie. After catching Danny in yet another affair, Anne leaves him and takes the children with her.
Anne embarks on a road trip across the United States, in search of a husband to fund a new life for her and her boys. George serves as the chauffeur. They first travel to Boston and Pittsburgh. Anne has a string of disastrous attempts at relationship. After finding that a former suitor now deems her too old to be of interest she becomes desperate and dispirited and chats up a man in a bar who turns out to be an undercover house detective. He takes her for a prostitute and charges her with solicitation.
Meanwhile, George meets with his father who comes into town on a tour. George asks him to take him back to New York but Danny turns him down because he is often on the road for his work. George concludes that Danny does not love him. George also learns that Danny had sent money several times, but Anne resolutely returned it each time.
Running low on funds, Anne tries her luck in St. Louis where her sister lives. The sisters have a very strained relationship but Anne tries to make the best of it and takes a job at a paint store and becomes engaged to the owner. It turns out, however, he is mentally ill and already married. Anne is paid off by the man's family for her trouble. As Anne readies to get on the road again, this time for Los Angeles, George informs her that he is staying with Anne's sister, whom he'd already cleared it with. Anne and George argue bitterly and Anne, resigned, accepts his decision and leaves with Robbie, who now serves as the chauffeur.
Near Albuquerque, mother and son get robbed by a couple they picked up for gas money. Robbie phones George to tell him what happened. In discussing it with Anne's sister and her husband, George discovers Anne had left money with them for his board and care. He takes the remaining money and meets Anne and Robbie at a Greyhound bus station somewhere in the Southwest.
The three arrive in Los Angeles and settle into a shabby apartment. Anne comes home one day to find Danny waiting for her. He asks if she still loves him and says he wants her and the boys to come back to New York. She replies, "I don't know if I love you but I do know I don't need you." Danny then departs extending an open invitation to return if she changes her mind.
Anne forges ahead and the family gets work as extras in a movie. Anne catches the eye of the movie producer and manages to get Robbie slated to try for a starring role. George thinks maybe his mother was right all along and everything will turn out fine. But that evening Anne gets a call and learns Danny has died of a heart attack. George flies back to New York to attend Danny's funeral and gets Anne's blessing to stay there and attend his former prep school on scholarship.
Soon, however, he realizes he belongs with his family and returns to Los Angeles unannounced. George finds Robbie having difficulty with a scene in a movie. As he helps Robbie recite his lines, George is discovered as a talented actor. Robbie gives up acting and goes to work in costuming. In epilogue, George reveals that he is a contracted Hollywood actor and has changed his last name to "Hamilton," which was his father's real last name. He realizes that Anne, Robbie and he didn't need anyone to take care of them, that they could take care of themselves and that they were going to be just fine.
