Keanu Reeves continues to demonstrate that he's among the most generous, good-hearted actors out there.

The 'Matrix' and 'John Wick' star is donating a quarter of an hour of his time as part of an online auction for Camp Rainbow Gold, a children's cancer charity based in Idaho.

Reeves is is offering a 15-minute Zoom call to the highest bidder in the nearly 50-lot auction. The call would take place on July 6th.

The actor will be on hand to answer the fan's question and maybe even share a virtual glass of wine.

Other celeb offers in the auction include a 15 minute private zoom concert from former Fifth Harmony member Ally Brooke; voice actor Rob Paulsen will mimic his most iconic characters from Jimmy Neutron to Pinky and the Brain, while also donating merch and a recorded voicemail message.

Offers also include: a signed Andy Grammer guitar; a spa day; custom tattoo design; and getaways to Mexico, a dude ranch, and Sun Valley.

Keanu Reeves has reportedly been quietly donating time and money to cancer charities in honor of his sister who battled leukemia for years now.

The campaign opens on June 15 at noon PST (8 p.m. on this side of the pond). It closes on June 22.

Here's where all the auction prizes can be found.

For those who miss out, you can next see Keanu Reeves on the big screen in 'Bill and Ted Face the Music'.
