The Flash is perhaps one of the most highly anticipated new Fall series, and fans will be even more excited about the show after hearing all news from the Summer TCA panel. Grant Gustin, aka The Flash, and the cast were joined by producers, who spilled details on the first season of the Arrow spinoff. We already knew that The Tomorrow People's Robbie Amell has joined the cast as Ronnie Raymond (half of Firestorm), but that's not the only fresh casting news. Take a look to see what we learned!
