Fox's 3D animated comedy Rio withstood the onslaught of Thor to earn $8.2 million this weekend (off 44% from last weekend). A $130 million final gross is still possible. However what really has taken the box office by storm is Paramount and Marvel Studios' Thor. It flattened out last weeks champ Fast Five for the number one spot. Thor is the latest on 3D movies news.

Having debuted overseas two weeks earlier than in the United States and Canada Thor had already grossed a mighty $133 million so far. And then it made its entry into the United States and Canada to kick off the first of four big comic book movies coming to theaters this summer. Debuting on a wide 3,955 screen count of which three quarters were either Digital 3D or IMAX 3D, the God of Thunder commanded a solid $66 million for its debut and a mighty per-screen average of $16,688.

Directed by Kenneth Branagh (Henry V, Hamlet) and starring Chris Hemsworth, Natalie Portman and Anthony Hopkins, the big-screen adaptation of the nearly 50-year old Marvel superhero tells the origin tale of a disgraced deity from the planet of Asgard who is banished to Earth by his father after reigniting an ancient war.The critics too have well received Thor giving it a 78% approval rating from Rotten Tomatoes. While the rating was not quite as high as the 94% given to 2008's Iron Man, the approval rating was higher than other recent Marvel efforts Iron Man 2 (74%), The Incredible Hulk (66%) and X-Men Origins: Wolverine (37%). Thor earned a "B+" from ticket buyers on Cinemascore with the under-18 crowd giving it an "A" rating.
