Keanu Reeves [SEP] Business and philanthropy
Reeves supports several charities and causes. In response to his sister's battle with leukemia, he founded a private cancer foundation, which aids children's hospitals and provides cancer research. In June 2020, he volunteered for Camp Rainbow Gold, an Idaho children's cancer charity. Reeves has said, "Money is the last thing I think about. I could live on what I have already made for the next few centuries". Reeves reportedly gave approximately $80 million of his $114 million earnings from "The Matrix" to the people of the special effects and makeup departments. However, this has been disputed. Reeves negotiated a back-end deal, relinquishing his contractual right to a percentage of the earnings from the ticket sales, to allow a more extensive special effects budget for the rest of the franchise.
