I predict Chalamet as MG is a hoax

The MG will be the real Bob Dylan. Because Chalamet played him in the movie, it'll be a twist to have a cast member go "ladies and gentlemen, Timothee Chalamet!" and when the camera pans to the stage, it'll be Dylan himself.

I base this prediction not on what I think is very likely, just on what I think would be awesome.
