Depends what you mean. 3D/360-degree? It's
sort of doable using cameras and software to stitch and interpolate all the different angles but you're still viewing from a fixed perspective. That works in the current crop of VR headsets. Same with 3D/180-degree (or similar wide angle but not 360 3D stuff). I've watched several on my Rift dev unit.
Getting into "real" 3D, like being able to view from any angle is trickier but there are experimental and in-development methods of doing this. The easiest works for CG stuff (just look at your 3D content in your headset). The more realistic it gets, the closer to a "movie" in 3D. Combining video footage with CG environments is a nice little "cheat" that's already been played with as well.
But the real challenge and (as I see it) the ultimate goal in this space is being able to use something like multiple light field cameras or RGB+depth cameras (think Kinect) arrayed around a room or environment and capturing both live video and the 3-dimensional structure of the surroundings and any objects or people. The depth data from the various angles needs to be combined and "textured" with the video data in order to create something approaching a real 3D recording of something over time (so maybe they'll need to advertise as 4D movies).
Even cooler is when you can compress all of this data and stream it over networks to be decoded on the other end. The result will be like 3D telepresence where you're all but transported to another location.
Microsoft has been working along those lines and it makes sense since they have Kinect and Hololens. This is the sort of thing that will be the real "killer app" for VR/AR as far as I can guess: https://www.youtube.com/watch?v=7d59O6cfaM0
