The room is 3D if we consider only space dimensions, i.e. x,y, z-axis. now if we introduce time as a dimension then any event happening in this room can be expressed by four dimension parameters.

Yes, a movie may be pictured 4D in future. Future technology can introduce many more amazing properties.

Actually, our world and all movies are 4 dimensional, as the 4th dimension is time. For 5 dimensional (additional space dimension) - I don't think it's possible to visualize it so human eye can see it. But you can make a projection of such movie to standart one which you will be able to see.
