4. Vince Vaughn
Notable Flops: The Dilemma ($70.5m against $70m), The Watch ($68.3m against $68m), Lay the Favorite ($20.9k against $20m) and The Internship ($76.4m against $58m). Clearly, audiences have just become a bit bored with Vaughn, likely because he hasn't picked a particularly enticing project in quite some time, opting for lazy comedies that make us yearn for the days of Swingers, and full-fledged classic studio pics like Wedding Crashers.
Upcoming Projects: Delivery Man has an uproarious premise - about a man who donates sperm as a youngster, and has 142 of the grown spawn filing to find out paternity - and could certainly become a hit, while the sure bet is without a doubt Anchorman: The Legend Continues, likely to be a far bigger hit than its predecessor.
