I was the visual effects producer for Rambo. I have been working on this movie since February of last year.
Some stats: The "there was no cgi in this movie" crowd is dreaming. There are 604 vfx shots in the movie. Approximately 2 thirds of them are blood or explosion enhancement. The shots were completed in 12 weeks of intensive work from September through December.
The vfx company is Worldwide FX, my company. We are a subsidiary of Nu Image/Millennium films.
Were there any particular sequences you are particulary proud of?
Two. The throat rip. Those shots were HARD. The blood coming between his fingers is entirely digital.
The other is the boat sequence. The one I pointed to in a post for the movie's thread in CD. While we were working on the movie I wasn't never able to ever make something that was too much for Sly. He always kept asking for more, MORE! When we were doing the shot of adding a bullet hole to the boat captain, as a joke I told my people, "make a tunnel through the guy. I want to see the control panel." I sent it to Sly, expecting to be told to tone it down. Instead Sly said, "Needs more blood". That's one detail out of the sequence, I'm really proud of the whole thing. None of the damage to the boat was real. None of the explosions on the boat were real except for the final one.
...but I will say that this IS CGI. CGI is "computer generated imagery". The blood was generated, the explosions were generated, the smoke was generated, the fire was generated.
...The guy who got his legs blown off was a digital leg removal. There was a LOT of stunt work. So we didn't have to do that many complete person replacements. Even the guys we replaced, we only tried to replace as little as possible of them. For example, when the guys were shot in half at the beginning of the last scene, we mostly used 2d body shifting with 3d blood added.
How much enhancement was needed on Stallone's kill of the Burmanese general?
That was entirely us. Nothing was shot gore wise. It was Stallone's idea to make the guy roll down the hill as two separate halves.
