Robin Williams reprises his roles as penguins Lovelace and Ramon in "Happy Feet Two" and says the animated comedy movie teaches about a very real threat.
In this film, which was released on November 18, main penguin Mumble, portrayed by Elijah Wood, and his family and friends realize that there's a very real threat to their home that forces them to band together to survive.
"You see it from their perspective," Williams, 60, told OnTheRedCarpet.com. "It's literally blocking them from food initially, and then escape, and then isolation - and then you realize that if they start to starve or become weak, there are a lot of other creatures that are just waiting to attack."
"Is it real?" he said. "Yes. Is it happening? Yes. Are there things you can do? Yes. People are trying to, but I mean these things are happening - these icebergs - they're literally called doomsday icebergs. Not to depress anybody, but it's real. Having some discussion about this isn't a bad thing."
Sofia Vergara, Pink, Hugo Weaving, Matt Damon and Brad Pitt also voice characters in the film. Williams described the special chemistry of working together as a team.
"Now people are reminding me that a lot of the other animations I did, I was alone," he said. "I guess because this one was such a great experience that I just thought, 'Oh, everything's like this' - like I'd forgotten the other ones. The idea of when you're together makes it easier - well not easier, you still work just as hard, but it makes it more fun."
One of the things Williams does when he isn't filming movies is performing comedy for United States troops overseas. He says the war in Iraq is a "tough fight."
"I've been there, I'm just wondering if they can keep up with what they say is going to happen," Williams said. "Even now they're [troops] saying, 'We're leaving, but not yet.' In Iraq, when I was just there this last time, they said by next Christmas we'll be gone - which is now ... time's up! But, if they have to stay, then they need to stay because certain things haven't been finished, but having been there, you see that it's a tough fight."
