20,000 Leagues Under the Sea – One of Walt Disney’s finest film works during his lifetime is this adaptation of Jules Verne’s 1870 novel. Kirk Douglas stars as a master harpooner who aids in the pursuit of a legendary giant sea monster, only to be joined by the legendary Captain Nemo and his submarine the Nautilus. With a masterful performance by James Mason as Nemo and remarkable action scenes that still hold up today, 20,000 Leagues won Oscars for Best Art Direction and Best Visual Effects.
