TEASER: "Happyish"

Showtime's new dramedy series was originally supposed to star Philip Seymour Hoffman- they had even filmed a well received pilot with him in the lead, but obviously the show was put on hold following his death. Steve Coogan now takes it on, sans an American accent, which I find refreshing. With all the British actors invading American TV shows lately, I don't know about anyone else, but I'm getting to the point where I can always tell if the person is American or not by the way they speak. Does everyone have to fake the accent? Especially if they suck at it- why not just be a Brit living in America? They do exist, right?
