Kind-hearted Keanu Reeves is known as one of Hollywood's nice guys for good reason, and it's not just because he flashes a wide smile to the camera crew and his make-up team.
The Point Break and Speed actor is one of the most generous film stars around and he refuses to keep all his cash to himself because of something quite personal.
Keanu - said to be worth a jaw-dropping £275m - hasn't let fame and fortune change him. In fact, he's let it change others' lives.
He is known to have donated 70% of his salary from the first Matrix film to fund leukaemia research. He then went a stage further.
He took it upon himself to make a difference simply because his younger sister battled the disease for 10 years.
Kim, now 55, was diagnosed with the blood cancer in 1991 - and he never forgot her battle.
Keanu, who was reportedly paid $10million upfront and earned nearly $35million for the first film in the 1999 franchise, was only too happy to write the cheque.
Let's not forget, this is the man who has taken numerous salary cuts so other actors would be paid more – even gifting stuntmen a Harley-Davidson each.
It's little wonder that he quickly gained a reputation as one of the most charitable and caring stars in Tinseltown.
He even set up a foundation of his own but despite transferring millions over the years, he doesn't even want people to know it.
Back in 2009 he told Ladies Home Journal: "I have a private foundation that's been running for five or six years, and it helps aid a couple of children's hospitals and cancer research.
"I don't like to attach my name to it, I just let the foundation do what it does."
He has previously said of his sister: "She was always there for me, you know. I will always be here for her."
Many also put the movie star's fantastic generosity down to the struggles he’s overcome.
He lost his girlfriend Jennifer Syme in a car accident in 1999, just 18 months after their daughter Ava was stillborn.
The hunk also saw best friend River Phoenix killed by a drug overdose in 1993
The 57-year-old admits he shied away from relationships for years after Jennifer’s death, preferring to form temporary families on the sets of his blockbuster films.
He says: “Working a lot and constantly moving from one film set to another has been important in helping me overcome some of the more painful times in my life.
“Every film set gives me the feeling that I’m part of a new family and I feel fortunate to be able to have a job that gives me a lot of satisfaction.
“But I still work at finding more inner strength and wisdom and hopefully look towards the future with greater optimism.”
