I sent this email to Deborah Groban:

Hello,

I hope this email finds you well in lovely Detroit, MI. I am very sorry to disturb you through your work email, but I am writing from [redacted] as a student extremely interested in your late brother's film "The Cure for Insomnia". I have followed the search for this film for some time now and wanted to reach out personally in an attempt to find this essential piece of film history. I am sure you have gotten many messages like this before, but I want to say that this film, although I have never seen it, means a lot to me as a form of extreme artistic dedication and I am willing to do whatever I can to watch it. Obviously, I am wondering if you have a copy of the film or know anyone who may possibly have a copy. I would be more than willing to pay for any necessary fees in digitizing, uncovering, repairing, or shipping a copy of the film. Thank you so much and I really hope to hear back from you.

Feel free to call me [redacted] or email me at [redacted]

Sincerely,
[redacted]
