Alfred Maskeroni, for Adweek:

Enter the new Vince Vaughn movie Unfinished Business, which comes out Friday. Twentieth Century Fox has teamed up with iStock by Getty Images to create a set of stock photos featuring Vaughn along with co-stars Tom Wilkinson, Dave Franco and others.

This is a brilliant viral stunt — one that I wish would catch on. Unfinished Business (trailer) opens March 6, 2015.
