Thanks Ayako.
A fan has posted a photo of Keanu from the Fundamental dinner that was held during the Beijing International Film Festival. Thanks for sharing @_ainur_!
Another fan has posted a photo of Keanu. Based on the hair it looks like it was taken during the MOTC shoot, perhaps during the Beijing phase. Thanks for sharing @lukassunnychan!
Finally, a fan posted her photo of Keanu. She chose a random Thai restaurant in Berkeley and ran into Keanu there. Shortly after getting back to the states from the Ronin shoot there were tweets and photos of him in the San Francisco area. All indications are that he was in the area on Side by Side business. The length of his hair is consistent with this. Thanks for sharing stacface4!
The photos have been moved to the gallery.
