SO, HOW LONG DOES IT TAKE TO PRODUCE A MOVIE??

Including ADR, (Automatic dialogue replacement) reshoots, special effects, CGI (computer generated imagery), special shots needing to take place (the protagonists gains or loses a great deal of weight, certain seasons or events are depicted,etc) and the normal delays due to financing, illness or unforeseen problems: 12-18 months. And many, many times years. It normally will take 2-3 months to film a movie + maybe 6 months to edit so much footage.
Some films are shot much faster and the discerning viewer will note this when they watch them as the continuity mistakes are rife and footage is often reused. Some major productions which have “built-in” sequels (The Hunger Games series, The Lord of the Rings trilogy, etc) are shoot simultaneously with scenes from one film being shot will those from another are filmed elsewhere.
