Character portrayal refers to the way an actor brings a character to life through their performance. This involves understanding the character's background, motivations, and emotions, allowing the actor to create a believable and relatable figure on screen or stage. Techniques such as method acting or improvisation can enhance this process, enabling actors to connect deeply with their roles. Effective character portrayal can significantly impact a story's reception, as audiences often form emotional connections with well-developed characters. Iconic portrayals, such as Marlon Brando in 'The Godfather' or Meryl Streep in 'The Iron Lady', showcase the power of an actor's interpretation in shaping a character's legacy.
