Have you seen any movies directed by Frank Capra like "It's a Wonderful Life"?
Miracle on 34th Street is similar
Yes.  They are both Christmas movies. He also directed "Mr. Smith Goes to Washington."  
Besides "It's a Wonderful Life" which is your next favorite movie directed by Frank Capra?
Maybe Meet John Doe... It's a Wonderful Life is much better.  Do you have a favorite director?
What is the plot in Meet John Doe? Have you ever thought about acting? 
A man needing money agrees to impersonate a non-existent person who said he'd be committing suicide as a protest, and a political movement begins.  No, I was in a play in middle school and like it but that's such a hard business if you want to pay the bills.
What if you could actually be on set of "It's a Wonderful Life"? Would you try it? 
Sure.  It would make me nervous but I wouldn't pass that up.  Would you?
Maybe...You would probably do great! You love that movie. Being nervous is a normal human experience.
