Speaking in an interview with TGS, the voiceover for Mario, Charles Martinet, has said he wanted to voice Link in a Legend of Zelda game, but was refused by Zelda creator Shigeru Miyamoto.
“I spoke to Mr. Miyamoto and said: “I wanna be Link, I wanna be Link”, and Miyamoto told me that Link isn’t going to have a voice; he is going to stay the way he is,” said Martinet.
“Of course Mr. Miyamoto is always right! The way it works right now is the way it is supposed to be. It’s the genius of Miyamoto and he knows just the right formula for making his games more fun and more exciting. For example in New Super Mario Bros. Wii, If things slowed down for Mario to express his inner feelings it just wouldn’t work and this way it keeps our hearts pounding with enthusiasm.”
