I don’t know if this is even relevant, but the IMDb says there were originally two additional lines in the theatrical release.
- An extended shot of Quirell, saying " I can’t master…" after Voldemort said “Get the stone.”
- An extended dialogue between Dumbledore and Harry, where Dumbledore mentioned that Harry’s father saved Snape.
Being someone who attended the 20th anniversary showing of the film in 4DX this past October, I can confirm that these two tidbits of dialogue are nowhere to be found in the print that was screened on that day. Who knows where the site got this information from? These two lines might be a nice find, though. 😏
