With everything that goes into a film, the cinematography, the music, the special effects, the one key thing that makes or breaks a film is the talent. You’ve got to have the right people in the right roles, or else the film’s gonna bomb. So what happens if you lose one of them mid-filming? You improvise.
These flicks here had the misfortune of losing their stars mid-way though production and had to find a way to complete the film and not make it obvious that their actor is no longer there. In most cases, it changes the dynamic of the film, while in other’s it’s painfully obvious that there’s a stand-in and not the actual actor.
Still though, you’ve got to give them credit for pulling it off.
