Casting is one of the most critical factors of filmmaking since it influences how audiences and critics view a film. It is the process of identifying the actors who can most effectively and convincingly step into the role. After all, actors are the ones that bring the script and concept to life, but choosing the wrong actor might render some parts untrustworthy, negatively affecting movies.
Even if the character is not a flatterer or an anti-hero, the audience must believe that their performance will stay appealing. For instance, please look at the Scary movie cast; every actor was perfect for their respective roles.
