The movie will explore the author's life and his writing career that included great children's classic The Hobbit in 1937 and in 1954 Rings trilogy.
David Gleeson, a sci-fi writer, has written the script for the under development project.
Tolkien had a fascinating life. He fought in World War I, where he saw countrysides torn to shreds and friends killed, and he was a code breaker in waiting during World War II.
He was close friends with CS Lewis, the author of the Chronicles of Narnia books, and the two made up part of an academic and writing group known as the Inklings.
It is not clear whether Tolkien's estate is involved in the biopic.
