In response to Josh Brolin being cast in Deadpool 2, [Ryan Reynolds tweeted](https://twitter.com/VancityReynolds/status/852272220575592452) the following: > The fuck, Fox! You can't play 2 characters in the same universe!! Josh Brolin was in Sicario and I was in Sabrina The Teenage Witch. I feel like there's a joke here I'm not getting. How are Sicario and Sabrina the Teenage Witch at all related?
