Which actor is most famously associated with "method" acting?

Marlon Brando is most famously associated with "method" acting, a technique developed by Lee Strasberg that encourages actors to draw upon their own emotions and experiences to create a more authentic performance. Brando's groundbreaking performances in films such as "A Streetcar Named Desire" and "On the Waterfront" exemplify this approach, as he brought a raw intensity and emotional depth to his roles that captivated audiences and critics alike. His work significantly influenced the acting style of future generations, including Robert De Niro and Leonardo DiCaprio, who also adopted elements of method acting in their performances. However, it was Brando who first popularized this technique within the realm of mainstream cinema, making him the actor most closely linked to the concept.
