Willem Dafoe is getting back in the tank.
The 58-year-old actor has confirmed he's reprising his voice role as the Moorish idol Gill in Pixar's highly anticipated Finding Nemo sequel, Finding Dory, which recently kicked off production.
"Yeah, I've already started," Dafoe told Total Film. "It's even better than the first. It's fantastic. It's good to say I think it's going to be better than the first; that's good advertising!"
The former Platoon man remained mum on the plot, which is said to focus on Ellen DeGeneres' Pacific regal blue tang, Dory, and take place about a year or so after the original as she attempts to reunite with her family.
Other characters from the 2003 box office hit who will be returning include Albert Books' clownfish, Marlin; his son, Nemo; and Gill's fellow "Tank Gang" members. New to the voice cast will be Diane Keaton and Eugene Levy as Jenny and Charlie, Dory's mom and dad respectively.
Dafoe's last notable big screen appearance was in 2012's Disney misfire, John Carter. He next stars in Lars Von Trier's sexually explicit drama, Nymphomania, alongside Charlotte Gainsbourg, Connie Nielsen and Shia LaBeouf.
But if you ask him, he couldn't be more thrilled about this latest aquatic adventure.
"It's difficult to repeat a success and so many years afterwards, but it's really cool," Dafoe added. "I've done one [voice] session so far and I just am going to have such a good time."
Finding Dory is slated to hit theaters on June 17, 2016.
It was originally scheduled to hit theaters on Nov. 25, 2015, but Disney has since opted to unspool Pixar's The Good Dinosaur in its place and push back Dory to give returning director Andrew Stanton more time to make a worthy follow-up to the Oscar-winning animated flick.
