Kristen Wiig

If you’ve seen any of Sia’s music videos or performances, then you’re familiar with a few things: one, that she never shows her face. Two, that she’s been using ‘Dance Moms’ star Maddie Ziegler as her mini-dancing-me. And three, that her videos feature passionate, inventive dance moves. A Sia performance is a real treat, and the one she put on at the Grammys last night was particularly delightful, as former ‘SNL’ star Kristen Wiig joined Sia and Ziegler on stage for an energetic rendition of “Chandelier.”

Merciful Zeus, if you thought Eddie Murphy returning to ‘SNL’ after 31 years for the 40th anniversary special on February 15 was big enough, wait until you get a load of the full roster. Rivaling turnout for the Emmys and Oscars combined, the upcoming ‘SNL’ reunion will feature everyone from legendary alumni like Bill Murray, Tina Fey and Chevy Chase, to favorite hosts like Alec Baldwin, and even Taylor Swift, why not!

Just when you thought Netflix’s ‘Wet Hot American Summer: First Day of Camp’ miniseries couldn’t get any bigger, after a first teaser confirming the star-studded cast’s return, Camp Firewood might well explode. In addition to the many guest stars already joining the ranks, so too will Kristen Wiig, Chris Pine, Jon Hamm, and Jason Schwartzman buddy up for Netflix’s ‘Wet Hot American Summer’ revival.

Since the news of an all-female 'Ghostbusters' was announced, we've all had lots of fun attempting to reverse-gender cast the film. Melissa McCarthy! Amy Poehler! Emma Stone!! All that speculation has come to an end. Director Paul Feig tweeted a picture of four women that serves as your an official reveal of the new 'Ghostbusters' cast.

Besides a funny opening monologue, the 2015 Golden Globes were kinda...boring? Which is weird, because the Golden Globes are supposed to be a lot of things, but boring isn't one of them. Their entire existence is pretty much to be the boozy, irreverent cousin to the Oscars. But, next year hosts Tina Fey and Amy Poehler won't be back to host (their three-year contract ended this year) and based on this awards presentation, we think they should give Kristen Wiig and Bill Hader a chance.

The narrative surrounding ‘SNL’ for the last year and a half is that it’s a show that’s “rebuilding.” And, yes, last season, that was true. But it’s weird: That narrative is still lingering even though, for people paying attention (I tend to pay attention), this 40th season has been very, very good. Last year, ‘SNL’ relied way too much on in-the-moment pop culture references (never a good sign). This season—including what we saw again during Saturday night’s Amy Adams-hosted episode—was all about great writing and great execution. It wasn’t quite as consistent as last week’s Martin Freeman-hosted show, but ‘SNL,’ right now, has a lot of momentum headed into its winter break. (When it returns with Kevin Hart, I really hope we see a sequel to ‘Z-Shirt.’ Please make this happen, Tim Robinson.)

Normally, when a guest host on ’SNL’ breaks into song during their opening monologue, it feels like a last resort, like no one in the writer’s room could come up with a better idea. And for a moment, it seems that way for Amy Adams, who talks about everyone really needing to enjoy their holiday season before the rest of the cast joins her to sing “We Need a Little Christmas.” But it’s all part of an elaborate set-up, since the great Kristen Wiig shows up to save the monologue and show Adams how to really celebrate the holidays.

The unfortunate and untimely death of the great Jan Hooks this past week sent the comedy world into mourning, with countless writers and comics stepping forward to pay tribute to the late 'SNL' star. It could have been easy for this week's new episode to gloss over the passing of one of their own (it is a comedy show, after all), but 'SNL' has always been a slightly class institution -- it remembers those who came before.

These days 'SNL' movies are a bit few and far between (come on, 'MacGruber 2'!), but at least some of their success lives on with legendary classics like 'Wayne's World or 'The Blues Brothers.' There have been 11 'SNL' movies total over the course of the last 40 years, but how well do you think you know the late-night sketch comedy legend's cinematic history? Test your knowledge with the latest installment of ‘You Think You Know Movies?‘

Reese Witherspoon, Kristen Wiig and Jennifer Aniston - three big name female actresses - all had new movies at the Toronto International Film Festival and each performance indicates a bold new direction for each of them.
