I am doing a tribute film for a physician that will be shown
at an American Cancer Society gala. Any ideas on some different
B roll to shoot? Will have the standard interviews with patients
and staff.

Get some photo's from the family/friends. Try to match them with what is being talked about in the interviews and cut to them for a few seconds then back to the interview. Depending upon what you get, you may be able to put together a nice intro or summary at the beginning or end. Hope that helps.
