Avatar made $73 Million in it’s opening weekend in the US, and over half of that was in the 3D version provided by RealD.

We congratulate our colleagues at 20th Century Fox on the tremendously successful release and spectacular campaign for ‘Avatar'” said Michael V. Lewis, Chairman and CEO of RealD. “This landmark weekend with over half of the box office coming from RealD-equipped theaters demonstrates that audiences have both discovered and are becoming loyal fans of RealD’s new generation of 3D.”

A good sign of more and better 3D films coming to theaters in 2010.
