Yet another spectacular director who repeatedly went home empty-handed from the Academy Awards. Sidney Lumet is one of the greats, having directed Oscar-nominated films like 12 Angry Men, Dog Day Afternoon, Network, and The Verdict, but never won.
In an attempt to justify their wrong-doings, the AMPAS awarded Lumet an honorary award in 2006. He may not have been as outspoken as say other filmmakers, but that's because Lumet let his work speak for itself, and his work spoke volumes. It's a shame the Oscar folks never listened.
