I took my standard Real D 3D ones and ended up with these huge IMAX ones.
I think the only difference is the style and size, because it was Real D 3D and not proper IMAX 3D.
I'm not sure if the standard ones would be big enough for such a big screen so you have to use the bigger ones.
I was going to test my standard Real D 3D glasses but got sucked into to the film when shit kicked off.
Even though Cineworld in Birmingham have a Digital IMAX screen and projector, they use RealD 3D and not Imax Digital 3D.
