Whats the difference between watching a movie in 3D and watching a movie in IMAX 3D?

1º the IMAX screen is huge compare to the common movie screen that use RealD. IMAx screen are as tall as a 7 store building! In most IMAX® theatre, these screens span from wall-to-wall and floor to ceiling. 2º , Reald is 100% Digital meanwhile, IMAX uses 70mm film which is the biggest size of the world!! Apart from the point that Digital proyectors are not as good as IMAX proyectors!,which delivers crystal-clear images at a level of quality that is far above ordinary projection standards, in both 2D and IMAX® 3D. 3º . The IMAX sound system is 3 times better than any other in the market, for example RealD. IMAX sound system has 14.000 watt of pure digital sound. I recomend you to go to IMAX is a unique exerience... you can read this article from LA times which is great talking about all the systems http://latimesblogs.latimes.com/herocomplex/2009/12/which-avatar-to-see-a-look-at-imax-dolby-3d-reald-and-boring-old-2d.html
