Melissa McCarthy: Capping off her successful year by hosting SNL. (Charles Sykes/Associated Press)

She caught the attention of American moviegoers in “Bridesmaids” and has capitalized on that by getting cast in several upcoming projects, including Judd Apatow’s “Knocked Up” follow-up, “This Is Forty,” and a comedy with Jason Bateman.

She scored an Emmy Award two weeks ago for her performance on CBS’s “Mike & Molly” and got her own beauty pageant-winning moment on live television in the process.

And this weekend, for the first time in her career, she is hosting “Saturday Night Live.” She’s come a long way from where she was five months ago, when I interviewed McCarthy for this profile and she said she was just hoping her turn in “Bridesmaids” would lead to some interesting movie offers.

Given her background in improv theater — like fellow “Bridesmaids” star Kristen Wiig, McCarthy is an alumna of L.A.’s Groundlings troupe — she certainly has the experience, as well as a fondness for playing unhinged characters, to bring some oddball comedic energy to Saturday’s late-night comedy mainstay.

Her promos with Andy Samberg for this week’s show are cute (see below). But here’s hoping that McCarthy takes this SNL opportunity to show off her decidedly, deliciously weird side.
