Yesterday, Collider hosted a screening of John Wick: Chapter 4 that was followed by a Q & A session with Chad Stahelski and Keanu. Steven Weintraub tweeted that he would be posting the Q & A in the next couple of days. He included a photo.
Thanks to @creativejace for sharing two photos from the screening on twitter here and here.
Thanks to Posh in Progress for sharing footage from the Q&A on youtube.
