Studiocanal has acquired worldwide rights to upcoming documentary “Fragments,” based on the eponymous book of Marilyn Monroe’s writings, diaries, poems and letters.

Liz Garbus, producer and director of Sundance 2011 hit “Bobby Fisher Against the World,” will direct. Stanley Buchtal, also a producer on “Bobby Fisher,” produces.

Exploring a “magical, unknown Marilyn,” Garbus said, “Fragments” went into production July 5. It will be ready for delivery by Aug. 5, 2012, the 50th anniversary of Monroe’s death.

Published last year in 17 countries, the book “Fragments” not only lifted the lid on some of Monroe’s most intimate thoughts, but recored her lifelong struggle for legitimacy, self improvement, and self-respect.

“Marilyn Monroe personifies the myth of celebrity and our film will explore these myths with wit, poetry and music,” Buchtal said.

As a film, “Fragments” will also go further.

Some of the world’s best-known actresses will read Monroe’s poems and letters. The movie will fuse documentary interviews, archive material — including never-seen photos and footage — live action, graphics, 3D creations and scripted elements.

Also, Studiocanal’s muscle as one of the Europe’s strongest sales agents can help “Fragments” reach far wider audiences.

“I am personally a big fan of Liz’s immense gift as a director and we are very excited about the involvement of so many talented people in making this movie a big theatrical event for us in 2012,” said Harold Van Lier, Studiocanal exec veep, of international sales.
