How to bend the camera view?, like "Entering the Warp zone"in the movie Interstellar

Is Camera View Bending possible in UE4?

How can i make the Rectangle Appear like an Semi Circle as shown below?

I would like to achieve this without meddling with the Static meshes. A solution with only Camera Manipulation would be nice.

You could tweak the camera’s FoV.
