At the Edinburgh International Book Festival, author Andrew O’Hagan announced that Angelina Jolie and George Clooney were set to star in a theatrical adaptation of his novel, titled The Life and Opinions of Maf The Dog, and of His Friend Marilyn Monroe.

Angelina Jolie will reportedly play the role of Marilyn Monroe, with George Clooney portraying Frank Sinatra. According to O’Hagan, the film “will shortly go into production”.

The project is currently without a director.

The synopsis of the novel, courtesy of Hyraxia, is as follows:

In November 1960, Frank Sinatra gave Marilyn Monroe a dog. His name was Maf. He had an instinct for the twentieth century. For politics. For psychoanalysis. For literature. For interior decoration. This is his story. Maf the dog was with Marilyn for the last two years of her life. Not only a picaresque hero himself, he was also a scholar of the adventuring rogue in literature and art, witnessing the rise of America’s new liberalism, civil rights, the space race, the New York critics, and was Marilyn Monroe’s constant companion. The story of Maf the dog is a hilarious and highly original peek into the life of a complex canine hero – he was very much a real historical figure, with his license and photographs sold at auction along with Marilyn’s other person affects. Through the eyes of Maf we’re provided with an insight into the life of Monroe herself, and a fascinating take on one of the most extraordinary periods of the twentieth century.

The Life and Opinions of Maf The Dog, and of His Friend Marilyn Monroe is now the third film about Marilyn Monroe in the works. The others, Blonde and My Week with Marilyn, will see Naomi Watts and Michelle Williams, respectively, portray the iconic actress.
