Okay from what I have gathered, the following mono mixes and 2.0 mixes of movies that have been includes in recent releases of movies as of 2010-2021 are…(Deep Breath)
Scarface (From a recent Blu-Ray that included the 2.0 mix)
Mad Max (From the recent 4k Ultra High Definition Disc)
Superman: The Movie (Included on the Superman Theatrical Edition 2006 and Onwards)
The Godfather Parts I, II, and even III (Depends on who you ask really)Wow. That was a very short list.
Now lets list some that were not restored with there original sounds…
The Terminator
The Godfather???
The Exorcist
Star Wars
…and so many more. 😦
The DIRECTOR’S CUT remix of The Exorcist is the revisionist one, the theatrical blu-ray’s 5.1 track has all of the original sounds with no changes whatsoever since the mix was created in 1998 before the director’s cut even existed
The Godfather on the blu-ray has the original audio as an alternative
