If some one want to make remake of a Film say one of the Ingmar Bergman's film some regional language of India, what is the legal process he should follow if there is any? I understand one cannot copy or shot exactly isomorphicaly, he will have to change the dialogue in some places and scenes too, but overall philosophy and idea of the film will be the same. Am I making any sense? If not please ignore my question.

[The following discussion is based upon my understanding of U.S. copyright law. Relevant law in other jurisdictions may differ in important ways.]
A film based upon an existing film (or book or play or screenplay) is an example of a derivative work under copyright law. The right to create such a work is a subsidiary right, in this case called the film rights, and belongs to the copyright holder. Before producing such a film, the filmmakers must purchase the film rights from the copyright holder. In practice, producers usually first purchase an option on the film rights, paying a percentage of the cost of the film rights in order to retain the exclusive right to purchase them during a specified time period. Thus, if the production of the film is approved by those financing it, they will be guaranteed that no one else has purchased the film rights already.
The film rights that are sold by the copyright holder do not usually come with any restriction on how the original work is adapted into a film. In the particular case of a film based upon a previous film, the filmmakers are free to copy the original film as closely as they like; scene-for-scene or even word-for-word. There are many examples of such "shot for shot" remakes listed on TV Tropes.
