Jack Nicholson is an American actor, director, producer, and screenwriter, internationally renowned for his often dark-themed portrayals of neurotic characters.

Nicholson has been nominated for an Academy Award 12 times, and has won three: two for Best Actor and one for Best Supporting Actor. He is tied with Walter Brennan for most acting wins by a male actor (three), and second to Katharine Hepburn for most acting wins overall (four). He is also one of only two actors nominated for an Academy Award for acting (either lead or supporting) in every decade since the 1960s; the other is Michael Caine. He has won seven Golden Globe Awards, and received a Kennedy Center Honor in 2001. In 1994, he became one of the youngest actors to be awarded the American Film Institute's Life Achievement Award.

Born April 22, 1937, his primary personality traits are represented by the Chinese Zodiac elemental animal sign, the Fire Ox. The Fire Ox is your proverbial "bull in a china" shop. HIs strong determination combined with Fire's impulsiveness makes him an Ox who all too often charges ahead without thinking about the (destructive) consequences. If he can control his emotions and summon up a reasonable degree of practicality, he will have the capability to do big things and will make an extremely loyal and responsible friend and family member.
