When asked what his dream role as an actor would be, he said that he'd love to portray a member of the Maori Battalion from WWII. He also said he'd like to play Tonto on The Lone Ranger, "just to remind the Ranger that he's not alone."
Manu came to be an actor in a roundabout way. As a young man, the girl he was dating, a ballerina, asked him to join her studio because there were no men in the dance class, and they wanted to perform West Side Story. He let her talk him into it, and wound up enjoying himself. Dance/musicals eventually led to straight acting.
