In making a 3D movie, you either shoot it that way (native 3D) or convert it to 3D during post-production. With the evolution of 3D movies, moviemaking has been on renaissance lately. In recent times however full 3D scan of actors can now be taken and inserted into future movies, this method is already been used in printing of props used in recent movies like the Guardians of the Galaxy.
3D has proven that no actor is indispensable. That is a lesson learnt from the completion of the movie Furious 7 by Universal Pictures on, after the death of star actor Paul Walker in a car accident in November 2013 about halfway through the shooting of the movie. Beyond saying the fact that the director James Wan had to cull footage of Paul Walker from the earlier films, Universal has declined to comment on what tech tricks were deployed to breathe life into Paul Walker’s character. Close sources however say that Peter Jackson’s Weta Digital was tasked with the sensitive and arduous task of completing and reanimating Walker for the completion of Furious 7, and the cutting-edge result points toward a possible future where most actors can be created seam¬lessly for any role in movie making if needed. Other movies like Gladiator had to create a digital mask from footages that was added to shots of a body double when Oliver Reed suffered a fatal heart attack on set.
Today, it’s possible to create an actor from scratch using digital composites. The Mill, for example, recently completed a 1 minute 30 second Johnny Walker ad for agency BBH in China featuring a Bruce Lee recreated in CG using previous shots for reference.
