Some film companies spend millions of dollars on the production of a single movie. Is it necessary to spend a lot of money to make a good movie? What factors contribute to the success of a movie?

It's common to hear that some film companies spend a lot of money, even millions of dollars, on movie production.

This

makes people ask if it's necessary to spend so much to make a good movie, and I personally believe it's necessary to invest so much money to achieve the range of elements that makes it a success.

Firstly

, all good movies are composed of good actors and even Hollywood stars, and these professionals have expensive salaries.

Besides

that, the recordings

last

for many months, which means, many salaries payments, accommodation and food need to be provided.

Secondly

, it's necessary to invest in a lot of technologies in order to get special effects creating situations that are not possible to do naturally.

Thirdly

, the film is not just made of movie stars, there is a large team behind the scenes, including directors, supervisors, cameramen, actors, dublês, maids, cleaners and a lot of others. And

lastly

, all the marketing and advertising take a good part of the budget, what is just fair, because there's no point in invest so much work, special effects, having the most famous people on that and not publicizing it properly.

This

is responsible for at least, 70% of the reach.
