I got myself a copy of "The Mask" on Blu-Ray and ran into some oddities with it and I want to know if anyone else has seen this.
Upon opening the disc in Makemkv the title of the disc is listed as Dumb_and_Dumber (something along that) and the disc itself appears to be 15GB which seems a bit smaller than usual.
Now I did play it, and it is infact "The Mask" but I was just curious if anyone else had this, and I want to make sure I didn't get some weird bootleg. I purchased it from GRUV so I'm confident it should be fine, but who knows.

The Warner Bros. release seems to be a single layer disc, so a 15GB sized movie might make sense: https://www.blu-ray.com/movies/The-Mask-Blu-ray/2056/

There seems to be a remastered disc from Arrow that's a dual layer disc: https://www.blu-ray.com/movies/The-Mask-Blu-ray/395181/

The warner Bros release is the one that I have, so I guess that explains the file size, but the disc name is still definently a bit of an odd one. I've had a couple discs that were named as some project name different than the movie, but this one is just named a whole different Jim Carrey movie haha

Upon further investigation my best guess would be that the manufacturer just misnamed this disc. It would appear that there is a double feature disc set with "The Mask" and "Dumb and Dumber" and the discs even include the same disc print as the one I received. More than likely just an error.
