This was probably the first movie I saw that gave me nightmares and I remember it almost made me sick to my stomach too. I think I was about 10 years old and I had been watching horror movies since I was 8, but this one put me over the top. I think it was in large due to the puking scenes when The Fly pukes on the jealous boyfriend a couple times.
Anyway, this is my all time favourite remake of any movie and the make up effects if simply amazing for its time. Jeff Goldblum is slowly transformed into a fly after accidentaly having a fly in the same transporter machine, which he invents. It's not your typical transformation either. He starts losing bits of his body and by the end he looks like a 6 foot tall creature from a Spawn comic or something. I remember the ending being very sad when I was younger as well and I felt so sorry for The Fly as he forces his girlfriend to kill him. Even though I'm a hugh Vincent Price fan and a B-movie nut this one is far better than the original and the sequal wasn't all to bad either.
