Cosmonova 70 mm film 

Most likely not, but I will ask around. Last time they gave a multi reason for not showing commercial movies. Technically there was no space for larger film plates in the projection room. The audience also sit very close to the screen so it would be difficult to follow a story since you would have to move your head around all the time to see even a little bit to the right or left.

There are like ten billionaires living within 2km radius of the museum, some of which could donate to keep the film projector system

@@EyesOfByes I bet its high on their priority list.
