Efron finds giving voice-over weird

London: Actor-singer Zac Efron, who is part of the animated movie ‘The Lorax’, says giving voice-over for the film was not what he had expected. The actor plays the lead protagonist Ted and admits putting his voice down for the part was not what he had expected, reported a website. "It was kind of weird. It was not what I expected. Luckily, I found out we got to record before it was animated, so we didn`t have to fit our lips into their mouths, which I always wondered if people had to do or not. So they animated to us. What they did is they let us do whatever we wanted, encouraged energy, spontaneity, and then they would take it away from there," he told a website. IANS
