He suffered from a stutter while growing up. A speech therapist suggested he audition for a play and it might help his speech. It did and he changed his major.
Was an usher at Dr. Martin Luther King, Jr.'s funeral.
Although he had been acting in small roles and in theatre productions, it was not until he was 40 years old that he received his first major role in Haz lo que debas (1989) and he was 45 when he became a star with Pulp Fiction (1994).
The success of Los Increíbles (2004) enabled Jackson to surpass Harrison Ford as the actor whose movies have grossed the most money in the world - in excess of $3 billion. (January 2005). Though in 2016, Ford re-surpassed him due to the massive success of Star Wars: El despertar de la Fuerza (2015).
Was an admitted drug user until he completed drug rehab two weeks before playing a drug addict in Fiebre salvaje (1991).

[When asked about his character in Star Wars: Episodio I - La amenaza fantasma (1999)] "He's black."
[on the subject of his character's inevitable death in Star Wars: Episodio III - La venganza de los sith (2005)] "I don't mind dying, I just don't wanna go out like some punk."
People mistake me for Laurence Fishburne all the time. And he always gets mistaken for me. (And why not? We've both starred in Spike Lee movies, haven't we?) Even when we're standing together, people have called him by my name and me by his. A woman recently ran up to him and said, 'My daughter loved you in Pulp Fiction (1994)! Could she have your autograph?' So he signed it, 'Respectfully yours, Samuel Jackson.'
To be frank, I am as passionate about golf as I am about acting. I very seldom get angry at golf. The year I started golf I had a caddie and one day I did get angry with myself and threw a club. My caddie told me, 'You're not good enough to get mad'. I have never thrown a club since. I enjoy my golf, it does not matter whether I play great or badly. I let it go.
I've played Loch Lomond - that's the one with the bogs isn't it? I played the one with the lighthouse. When we were in Liverpool we used to take the ferry and go to Northern Ireland. Films get in the way of my golf, but they have afforded me the chance to play a lot of golf.
