I watched the first episode of The Riches the other day and was also highly distracted by Eddie Izzard's accent. It was exactly the same as the one he uses in his shows when he's pretending to be American for comedic effect so I kept expecting him to tell a random story or say something funny. And he didn't. It just didn't feel right. Not sure that I'll be watching the rest of the series - I found it a bit of a trial overall.
