No. These will likely never be seen by the cast and crew (as I'm little more than a pseudonym on a forum). This is a personal interest to see where the interested society flows.

If you could ask one (or more) of them a question (or more), who would you ask and what would you ask?

The obvious ones (asked ad nauseum):

• Any: Will there be a sequel? (Answered likely as much as we're gonna get: They don't not want to do a sequel.)
• Any: Who will be in it? (They never actually said there was going to be one.)
• Any: Is Penny really dead for good? No clones? No twins? (Given M.E.'s past, it's anyone's guess, though I like my own guess, personally.)
• Mrs. Trpcic: How does one pronounce Trpcic? (It's pronounced like Terp-cheech. It's Croatian.)
• Any: What are the song names? (We keep getting little bits here and there.)
• Any: Will it be available internationally? (Yes.)
• Any: When will it be available internationally?

Now, for my quick list:

• Mr. Whedon (the Joss one): After reading about Dollhouse, does your psychiatrist know you just want to mess with our minds, making us dig into those uncomfortable places we avoid in there?
• Mr. Harris: Do you like playing “good guys” or villains better?
• Mr. Fillion: Same question.
• Ms. Day: How much of “you” is in the characters of Penny and Cid?
• Mr. Helberg: That role looked so uncomfortable. How did you stand being slightly wet the whole time?
• Mr. Helberg: How do you feel knowing that Mr. Whedon (the Joss one) thought he should have cut one of your best lines?
• Mrs. Trpcic: What was your favorite costume in Dr. Horrible?
• Mrs. Trpcic: What's been your all-time favorite costume?
• Any: What advice would you give to someone looking to break into your respective specializations? (If you say “don't”, I'll send evil thoughts your way.)
• Any: How do you handle fame without losing your cool and breaking a few (or more) cameras? (Do you count backwards from ten while taking deep breaths or something?)

Please add your own. Since nobody but us will likely read it, feel free to dig into those uncomfortable places they might avoid. This is make-believe. Don't forget that there's a lot more than just those people above.
