I remember when Fear the Walking Dead was about to premiere, and I was excited because it was going to cover the beginning of the Zombo takeover. But then in one episode, there was a 9-day time skip, and in that 9 days, civilization had collapsed. That was the part I wanted to see, and I was crestfallen. Stephen Dillane's kid was on that show (I don't know if he still is). Meaning Stephen Dillane has watched Fear the Walking Dead. That makes me laugh, for some reason.
Also, Harrison Ford has likely watched at least the first season of Supergirl. I want that commentary track.
