You would have to get the people responding to flyers to edit the link to contain their e-mail address for the system to notify you.
However, I think anyone who watches your movie (http://website.ws/YOURACCOUNT/show) adds to the count for the number of people who've watched.
Designing the flyers to contain your e-mail address is probably your best bet. People who are seriously interested wouldn't mind contacting you, right?
