Plus there are plenty of draws to seeing a movie in IMAX, regardless of 2D or 3D.
Imax Entertainment CEO Greg Foster confirmed that, “The demand for 2D films is starting to exceed 3D in North America.”
Blade Runner 2049 will only be shown in 2D in IMAX when it’s released this fall.
On the other hand, 2D is cheaper, and plenty of folks eschew 3D because it’s too expensive, it gives them headaches (guilty), or plenty of other reasons.
