US-based Marcus Theatres, a division of The Marcus Corporation, has secured a deal to install six new RealD 3D systems across its portfolio of cinemas.

The company plans to install the six additional 3D systems in time for the December 18 opening of Avatar, James Cameron's highly anticipated 3D release.

The new RealD installations will be introduced at Sheboygan Cinemas in Wisconsin; Chicago Heights Cinemas and a second 3D screen at Orland Park Cinemas in Illinois; Elk River Theatre and Shakopee Town Square in Minnesota and 20 Grand in Omaha, Nebraska.

With the addition of the six RealD 3D equipped screens, Marcus Theatres will offer digital 3D at 32 locations in seven states.

Bruce Olson, president of Marcus Theatres, said: "Expanding our digital 3D footprint is part of our growth strategy, as the studios produce more and more digital 3D films. With up to 14 digital 3D films scheduled for release in 2010, this powerful technology is expected to continue to have a positive impact on our box office." said Bruce J. Olson, president of Marcus Theatres.
