So I just watched the original and compared with the extended versions (the weyland dialogue & the final fight)
To me the Theatrical cut is ruined, (I wasn't happy with it anyway) it feels like a joke, seriously the last scene is like an insult,
-David: "he's coming"
-E.Shaw: "Who's coming" (stupid question in both versions)
-computer: bip bip
-Engineer: Aaaaarrrrrr !!!!
-E.S: "Diiiieeee!!" pushes a buton hentai monster grabs engineer
Total 25 seconds long
