Who are all the celebrities in the subreddit main picture?

Who are all the celebrities in the subreddit main picture? This one: https://i.imgur.com/TbiGM6J.png (you can only see it if you're using the old design of reddit and from PC). I can only recognise Samuel L. Jackson, Morgan Freeman (seems like him), Marilyn Monroe, Rowan Atkinson, Nicole Kidman, Carly Simon and James Earl Jones. (I also recognise the other celebrities but I don't remember their names, it may also be because I'm not from the US) I'm asking because I'd like to watch their interviews about stuttering. They're really inspiring in most of the cases. Thanks guys!
