broadwayworld.com, Rose Hemingway (co-star How to Succeed in Business Without Really Trying) also mentioned Daniel. Thanks to dr.de for the tip.
How has it been working with Daniel Radcliffe and John Larroquette?
Sadly I am not in very many scenes with John so we have not had much chance to work with each other, we have one scene with a few lines and that is all. But he is lovely. And Dan, Dan is incredible He is a wonderful person, and he has such great energy and he comes to work every day ready to get things done and to work and to learn, he's got this infectious energy around him and that is a lot of fun. We're buddies, so we have a good time.
