Many thanks to @veeveeveeveevee for sharing on twitter. He shared his the photo that he took with Keanu Reeves today on instagram. He ran into Keanu at the movie theater where The Dance of Reality, also known as La danza de la realidad, was being shown. The photo is here.
For those interested, the film was made by CHilean filmmaker Alejandro Jodorowsky. There is a blurb about it here.
