Willem Dafoe has confirmed exclusively to Total Film that he’s returning for Finding Dory .

In fact, he’s already started work on Pixar’s sequel to , reprising the role of moorish idol Gill.

“Yeah I’ve already started,” Dafoe says. “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!”

Though he wouldn’t be drawn on the film’s plot – which will focus on Ellen Degeneres’ titular regal blue tang possibly reuniting with her family – he was confident that Finding Dory would repeat Nemo’s success.

“It’s difficult to repeat a success and so many years afterwards, but it’s really cool,” he says. “I’ve done one session so far and I just am going to have such a good time.”

Finding Dory opens on 17 June 2016.
