I've got an idea for a shoot involving about 10 - 20 people around a model in a public area.  The "extras" will be doing things like they would in their normal lives (still under "general" direction though), and the model will be the primary focus of the image.  Do I need to get releases from all of them before I could do anything with the images?

If in doubt, get the Model Release out...
