Gill is a moorish idol fish and a supporting character in the animated film Finding Nemo. He is voiced by Willem Dafoe. He is a close friend with Nemo whom he met at the dentist's fishtank in Sydney, Australia. He is the genius behind the idea of getting Nemo and the others in the tank to escape by stopping the rotating machine with a pebble. When the plan unfortunately failed almost resulting in Nemo's life, they thought of a better one the next day when there was a special fish tank system put in place. Nemo faked dying and after a matter of crazy things happening he went down a drain and was never seen by Darla again. A few days after Nemo is finally reunited with his father, Gill and the others from the tank are shown to have escaped and are swimming happily in the ocean.
