It’s also not expected to repeat its box office victory, which saw Mumble and his friends beating even James Bond himself in Casino Royale back in 2006. With The Twilight Saga: Breaking Dawn: Part 1 expected to earn at least $100 million this weekend, Happy Feet Two has virtually no chance of opening on top, but Box Office Prophets┬áis still expecting a strong debut of $45 million.
