Jack Nicholson is one of Hollywood's most iconic actors, known for his devilish grin and intense performances. He holds the record (tied) for most Oscar-nominated male actor with 12 nominations, winning three times. His unforgettable performances include McMurphy in "One Flew Over the Cuckoo's Nest," Jack Torrance in "The Shining," and The Joker in "Batman." Nicholson's ability to play both leading men and character roles, often with a hint of madness, made him one of the most versatile actors of his era. His larger-than-life persona both on and off screen made him a cultural icon.
