3. Megan (Bridesmaids)
Its often a recurring theme in Comedies, that the central character is actually quite dull - or at least, not as funny as the eclectic group of individuals with which he or she has surrounded themselves. This is defiantly the case with Bridesmaids, and Kristen Wiig's calamity character has got a fantastically funny posse with which to bounce the jokes off. The stand-out performance however, is Melissa McCarthy's loud-mouth Megan. She doesn't care what people think of her. She doesn't care that her actions are frowned upon. And it is because of this, that she causes offence to a number of the other characters in this rampant comedy. Quite frankly, anyone that takes a crap in the sink of a Wedding Shop bathroom is always going to cause a stir.
And to demonstrate my point... "I'm glad he's single because I'm going to climb that like a tree." - You do that Megan, you do that.
