Cassel used to be a popular choice for Joker in the pre-Heath days.
These guys are BY FAR the best options for the Flash
I used to support connecting Arrow and MOS, but Amell and Gustin are not up to par. I wasn't the biggest fan of Gustin's performance last night. It was serviceable, but I wasn't impressed at all. He's not the "perfect" Barry Allen that people are making him out to be.
I think people are just so excited about the idea of seeing Barry Allen in live action that they're willing to trick themselves into thinking that Gustin was excellent, when he really wasn't.
Honestly, that dude was mediocre by Arrow's standards. His role had so much hype, but his performance imo was one of the weaker ones of the season. Poor dude, there was so much hype to live up to.
Gustin would be hindering Flash's potential if he was the big screen Flash too. We need movie quality actors to be considered.
Gosling and Aaron Paul are definitely my top choices.
Gosling is a bit unrealistic, but I can see this role going to Aaron Paul. He's still not a massive movie star, and would still be kinda cheap, but his acting is Oscar quality. We'd be in for something truly special if either Paul or Gosling were cast as Barry.
