I was about to suggest you to go look at the 9 pages of pictures for this show on IMDb.com but when I went on Disney+ to start watching the Marvel Show "Secret Invasion" I saw that The Company You Keep is on Disney+ !!! lol Go see if it's there for you, if not in the Recently Added section, search with his name. Or at least, it might be available soon.
