Though Melissa McCarthy's star went supernova just five years ago in a role so popular that she won both an Oscar nomination and an Emmy statue (Bridesmaids... oh please, you know the Emmy wasn't actually for Mike and Molly!) she's wasted approximately zero days since in cementing her unlikely place as a box office titan with star vehicles emerging annually since. Right now that means her new capitalist diva comedy The Boss and if it isn't Spy (2015) or The Heat (2013) level funny (sorry... but few things are) it's not bad. It sure as hell runs rings around Identity Thief (2013) and Tammy (2014) so it's firmly middle of the pack, if you ask me. (It's weird that the reviews so far are the worst of any of her solo vehicles.)
We call her place as a truly bankable actress 'unlikely' because it's just that. Guess how long it's been since audiences embraced a hefty actress as a (regular) lead? I can't think of a single one from my lifetime though we occassionally get a one time debut hit (Gabby Sidibe in Precious, Nikki Blonsky in Hairspray - they had to settle for supporting work thereafter) or a frequently employed secondary lead (Rebel Wilson). You might argue for Kathy Bates but she's only headlined a few times. I think you have to sail back to the early 1930s to the odd case of Marie Dressler who was a true box office sensation and quite awesome (see her Oscar winning Min & Bill; It's a blast!)
Though Bridesmaids entirely changed McCarthy's career her debut was way back in the cult favorite Go (1999) which she soon followed with the role that most people think of as her debut "Sookie" on several seasons of The Gilmore Girls, a role she'll reprise for the upcoming reunion. Hooray! All the McCarthy movie posters are after the jump. How many have you seen?
