There were multiple tweets today coming out of London indicating that there was a screening of Side by Side at the Pinewood studio. I replied to one of the tweets and asked if it was a closed event for people in the industry. The gentleman replied that it was. From additional tweets that emerged aftewards, it became clear that both Keanu Reeves and Justin Szlasa were both in attendance and held a Q & A session afterwards.
We can now confirm that this event was a special screening for the British Society of Cinematographers. The entire article can be read here.
