London, March 26 (ANI): John Lennon's half-sister Julia Baird, 62, and the makers of a new biopic on the late Beatle's childhood face possible legal action from American author Geoffrey Giuliano.
The writer has penned several books on the Fab Four, apart from collaborating with Julia for the biography 'John Lennon, My Brother', published in the late Eighties.
While Julia wrote a second book titled 'Imagine This: Growing Up With My Brother John Lennon' in 2007 without Giuliano, the author claims that the tome is based on his previous research into the musician's life.
He claims that half of Julia's earnings from the upcoming biopic 'Nowhere Boy' should be given to him, and plans to pursue his case in the courts.
The movie stars Kristin Scott-Thomas as John's aunt Mimi and Anne-Marie Duff as his mother Julia.
Giuliano claims that he persuaded Julia to work on the Lennon book shortly after they first met at a 1986 Beatles convention in Liverpool.
"In doing my own research, I filled in a lot of blanks for her. More than half the material in the book is a result of my research," the Daily Express quoted him as saying.
He even claims that the new material that appeared in Julia's subsequent, more recent book on Lennon, including the fraught relationship between Mimi and their mother Julia, was a result of his original findings.
"Aadditional information in Imagine This was uncovered by me in my original research. I was the person who conceptualised the original book," he says.
Julia's publishers were unavailable for comment. (ANI)
