OMG! Is that a open Matte print I see? The Blu-ray has a aspect ratio of 1.85:1, so your print at least has the benefit of extra picture information.
this is an old topic, but extra picture isnt always a “benefit”. The filmmakers never intended for that area to be seen. Its obvious even in these shots. Lens vignetting is visible, and there is odd framing for the actors.
regardless, this is a cool thing to see.
