“The man who knew infinity” (2015, Matt Brown with Jeremy Irons and Dev Patel),
It is not exactly what you asked, however, it starts presenting, briefly, for one minute, Hardy (Jeremy Irons) MC, and quickly switches to IC POV, Ramanujan’s youth in India (Dev Patel). It takes 15 minutes to see MC again. It’s an interesting movie in Dramatica terms, as the protagonist is the IC.
It could be helpful to think about what would happen if the first minute of the movie was removed. In my opinion, it would not change anything if we knew, at some point, that the narrator of the story is the MC.
