CBC has announced that it will show "Queen Elizabeth in 3D" on Sept. 20 at 7 p.m. ET.

A special TV won't be necessary to view the program in 3D, but viewers will need to pick up 3D glasses to experience the effects. Two million free pairs will be available at Canada Post in early September on a first-come, first-served basis.
