While Katharine Hepburn holds the overall record for actors with four wins, Daniel Day-Lewis holds a specific and prestigious distinction: he is the only person to win three Academy Awards for Best Actor in a Leading Role. He won for 'My Left Foot' (1989), 'There Will Be Blood' (2007), and 'Lincoln' (2012). Known for his extreme method acting, Day-Lewis often stayed in character for months at a time. Other actors like Jack Nicholson and Walter Brennan also have three Oscars, but their wins are a mix of Leading and Supporting categories. Day-Lewis's perfect '3-for-3' in the lead category cements his reputation as one of the greatest performers in the history of cinema.
