I know most people do things like take exterior footage of buildings, subjects to be interviewed walking in and out of said buildings and rooms, and walking in a straight line somewhere or throughout an interview location. What else can be taken to create this type of footage? If you're interviewing someone in their home, do you take footage of them fake reading a book? Cooking something? Taking a phone call? Watching television? What about someone at work? Walking around the office? Typing on a computer? Taking a phone call at work? Having a lunch break? Have you filmed interviews before? What did you do to create B-roll footage for them? What types of environments were you in when you filmed them? What came to mind when you had to make something up to film? If you know of others who have filmed B-roll for that purpose, how did they film theirs? Currently film theirs?
