Robin Williams believes doing voiceover work on 'Happy Feet Two' was like being on a ''paid vacation''.
Robin Williams finds doing voiceover work like "a vacation".
He said: "Doing the voice is a gift. It's literally like a paid vacation where you go to Australia and work with these guys for two weeks and then come back.
"The weird thing is how long it takes - three years. I think when we did the first sessions, it was a year ago since we did the last session."
Robin particularly enjoyed recording the film with fellow stars Elijah and Sofia Vergara because they are both so "sweet".
He added to HeyUGuys.co.uk: "It's really great coming back because it's the same people. All the amigos were these Latin comics and add to that Elijah who's the sweetest man in show business and on top of that you have SofÃa Vergara. She's so sweet and so sexy and is just a gift! She makes the room 3-D! It was like a reunion."
