According to The Hollywood Reporter, Gibson – originally attached to direct – will star as Murray while Sean Penn will play Dr. W.C. Minor, a mental asylum inmate who submitted over 10,000 entries.
A few years after directing Braveheart to Oscar-winning glory in 1995, Mel Gibson acquired the film rights to novel Professor and the Madman.
Penn’s most recent film as director is The Last Face which premiered to negative reviews at Cannes Film Festival in May.
Only now – two decades later – is the Australian actor-director ready to move ahead with the project.
