In 1999, Keanu Reeves became most famous for his role in the groundbreaking science fiction film, The Matrix.

It earned an impressive $463.5 million at the box office and was nominated for and won four Academy Awards. The Matrix is a happy story in a lot of ways, but the life of its star wasn't always.

Now 50 years old, Keanu's life has been full of more tragedy than you would expect from a movie star. Despite each setback, he's kept pushing forward. It's helped develop himself into the awesome person that he is on and off the screen.

At the age of three, his father left their family. They stayed in touch for a few years, but after the divorce and moving from city to city, they fell out of contact.

Keanu attended four different high schools and struggled with dyslexia, making his education more challenging than it is for most. Eventually he left high school without earning a diploma, though through sheer will, he is an avid reader now.

At the age of 23, his closest friend River Phoenix died of a drug overdose. During a Reddit AMA last year, Keanu said: "He was a remarkable human person and actor. We got along very well, and I miss him. I think of him often."
