If you could talk Rupert Grint and Emma Watson into starring with you in a play or musical, which one would it be?
Daniel Radcliffe: I'm thinking of things that have one girl and two guys, and the first one was Merrily We Roll Along. Let's go with that.

Every show experiences technical difficulties. What was the worst technical difficulty experienced during your show and how was it handled?
Dan: There was a point when our revolve stopped turning during a scene. Fortunately, it had come round enough so we could do the next scene. They tried to bring the curtain down but it wouldn't, so we had to leave the stage so our crew could go to work and cut out a frayed cable in the revolve. I think we stopped for a maximum of ten minutes. The crew is fantastic.

What was the most "interesting" present someone gave you at the stage door?
Dan: I've been given lots of cow-themed things because of Billy's fascination with cows. I still get given, lots of people give this to me, books of photographs of myself. They compile them like a scrapbook, which is really sweet, but I don't know how vain they think I must be to look at posed photos of myself. There's been nothing too creepy or freaky, which is good.

Why did you choose to return to Broadway in an ensemble piece such as this, as opposed to a star vehicle like Equus?
Dan: I guess I didn't look at it and say, "This is a great part"; I looked at the play and said, "This is a great part in a great play." I just thought I'd be doing a great play. I didn't realize at the time that I'd be getting three scenes off in the middle, which was lovely. In How to Succeed, when I wasn't onstage, I was changing, so it was very busy. It's very nice to do a play where you do get some time to yourself. And working with such a great ensemble has been really exciting.

"Everyone sort of expects — because the characters he's known for are quite brash, obnoxious and loud — everyone sort of does that thing where they equate the character with the person and he's not like that at all," Radcliffe told Mashable.

"He's like a really sweet, humble, smart guy and brilliant at improvising," he added.

"I hope he takes some of his amazing improvisational skills to the new Star Wars movie."

"And they're filming it where we filmed all the the Potter stuff," Radcliffe added, "so I'm going to try and get a set visit."
