You absolutely need to see Casey as Marty, he was brilliant even in the second preview! And yeah Roger is utterly fantastic, I saw him in Manchester, London and then in NY, he was born to play the role of Doc Brown! 😊 glad you loved the show
I've worried about "Back to the Future" getting a reboot or a soulless sequel given the trends from Hollywood in recent years. I wouldn't have predicted it showing up as a musical, but it sounds like that was the right choice.
