You might not know Alexander Gould by name, but you'd definitely recognise his voice. He's the kid that provided the vocals for titular clownfish Nemo in the original picture. Now, more than a decade later, he's all grown up. Which means, of course, that it was impossible for him to provide the voice of Nemo in the upcoming sequel, Finding Dory, because he's 21-years-old and that would be weird. The story is set just six months after the events of the first picture, after all (because fish don't live that long?). A young voice actor named Hayden Rolence - still a child, thankfully - has been hired to voice Nemo for Finding Dory in the wake of Gould's departure. Annoying when you're the lead character in a billion dollar franchise and you can't even reprise the very role that you made famous, isn't it?
