'Cars 2' rules weekend Box Office

Although Cars 2 may not be that great, people are definitely packing into theaters to see it. Box Office Mojo reports a take of $66.1 million at the domestic box office.

That puts the flick's opening numbers at the fifth best for a Pixar movie--it's almost tied with Up which opened at $68.1 million.

It's playing in 4,115 theaters, and is expected to remain strong throughout the next couple of weeks, although the new Transformers this weekend and the final installment of Harry Potter next month very well might lure audiences from unloading their wallets into Emeryville, especially after how the critics received Cars 2.

However, Cars 2's revenue stream is really gonna come from merchandising, seeing how Cars is the current merch champ among any other Pixar film, at over $5 billion in sales (and that's as of April 2009).
