I wish to know if someone could write a story, would they write the character with an actor/actress in mind, or would they develop a character from inspiration and cast someone aptly? Both approaches occur, but what would you prefer?

Because great directors like Martin Scorsese and Tarantino often cast actors like DiCaprio and Samuel Jackson repeatedly in their movies, are they writing characters specifically for them, or are these actors simply suitable for the directors’ vision?

Apart from the business perspective, many still prefer the story to the cast. The success is not fathomed by the box office collection, the impact of the flick is the real success imo.

I believe that a good artist with strong writing is essential for success. If I write a character for an actor I like, they may not resonate with the role and decline involvement. What could you do in such a scenario?
