My friend Boo has a film troupe called F is for Film.  They spoof popular movies and trends.  Their troupe consists of 7 people at the moment, so that was group shots and single shots of everyone including a headshot type thing.  There was a theme, film at the end of the universe or the end of the world or some kind of film in the future doomsday idea.  They found this awesome empty floor of a building that was under construction.  I kind of went the Men in Black route when asking them to pick costumes.  The fun part of groups is finding each individuals personality and bringing it out in facial expressions and body language.
