Ana de Armas has shared a photo from the set on webstagram. She tweets a lot and those who are interested can follow her here.
Update: Many thanks to potatosmasher170 for sharing two photos that he took of Keanu on the set on webstagram. The photos were posted about an hr ago. Keanu has on the same clothes as in the photos from yesterday. It is not clear when the photos were taken but it is conceivable that they are filming scenes today that are a continuation from filming yesterday. Photos are here and here.
