Dear Frankie

Dear Frankie is a 2004 British drama film directed by Shona Auerbach and starring Emily Mortimer, Gerard Butler, and Jack McElhone. The screenplay by Andrea Gibb focuses on a young single mother whose love for her son prompts her to perpetuate a deception designed to protect him from the truth about his father.

Through a Glasgow post office box, Frankie maintains a regular correspondence with someone he believes to be his father, Davey, who allegedly is a merchant seaman working on the HMS Accra. In reality, the letters he receives are written by his mother, who prefers maintaining this charade instead of telling the boy the reason she fled her marriage.When she learns that the Accra will soon be arriving at the docks at Greenock, Lizzie in a panic concocts a scheme to hire a man to impersonate Davey. When her effort to find someone at the local pub fails, she enlists Maries assistance. Marie arranges for her to meet an acquaintance who coincidentally is passing through town at the same time the Accra will be in port. When Lizzie and the stranger Gerard Butler meet, he doesnt tell her his name. Lizzie explains the situation and gives him the letters to provide some background. He agrees to spend a day with Frankie in exchange for the meager payment Lizzie can offer him. ........
