These are IMDb's top stars of 2016

Margot Robbie (Suicide Squad's Harley Quinn) and Emilia Clarke (Game of Thrones' Daenerys Targaryen) lead IMDb's top 10 stars of 2016.

Robbie (No. 1) and Clarke (No. 2) are part of a class of actresses with powerful characters who dominated the list, determined by page views of the movie site's 250 million monthly unique visitors.

Stranger Things' 12-year-old 2/19/04 star Millie Bobby Brown landed third, along with Deadpool's Morena Baccarin (No. 5), Wonder Woman Gal Gadot (No. 6), The Danish Girl Oscar winner Alicia Vikander (No. 7), Star Wars: The Force Awakens heroine Daisy Ridley (No. 8) and The Girl on a Train' s Haley Bennett (No. 9).

"These actresses are portraying remarkable female characters at the center of movie action this year, often protagonists in genres where women just didn't excel before: action, comic books and sci-fi," says Keith Simanton, IMDb's senior film editor.

Robbie has been a force on IMDb's annual list since breaking out as Leonardo DiCaprio's screen wife in 2013's The Wolf of Wall Street (she ranked third in 2014 and 2015). In 2016, Robbie starred as Jane Clayton in The Legend of Tarzan and bat-wielding antihero Quinn, who immediately broke out of Suicide Squad's pack.

"She just popped. People just got it," says Simanton. "It's such a unique role and look, and Robbie was perfect casting."

Clarke maintained her second position from 2015's list as GOT's dragon queen, further boosted by her role in the sleeper hit Me Before You with Sam Claflin.

"Emilia's obviously on the list because of Game of Thrones. But you cannot dismiss how popular how Me Before You was," says Simanton. "Those two things combined propel her in 2016."

Exclusive: Tom Hardy dethrones Shailene Woodley as IMDb's top star of 2015

Tom Hardy, who topped 2015's top 10 list, hit No. 4 for 2016, alongside his The Revenant co-star Leonardo DiCaprio (No. 10), who won his first Oscar in February. "The Revenant was the talk of winter's awards season and these guys are just huge stars," says Simanton.

Brown also leads IMDb's top 10 breakout stars of 2016, featuring stars who landed among the site's annual 100 for the first time in their careers. As the buzz-cut, supernatural Eleven in the Netflix series, Brown prompted curiosity and Internet searches. "Millie Bobby Brown is a classic example of people wanting to know 'Who is that?' " says Simanton.

Brie Larson appeared fifth among breakouts after her 2015 drama Room, for which she won a best actress Oscar. She cemented her star power by being cast in two event movies, Kong: Skull Island and Captain Marvel. 

The breakout list also featured Evan Rachel Wood (No. 6), Dolores Abernathy in HBO's Westworld, and 50-year-old 4/22/66 Jeffrey Dean Morgan, who made an impact as bat-smashing Negan in AMC's The Walking Dead.

"The Walking Dead is finally getting Jeffrey Dean Morgan truly recognized after his long career," says Simanton. "That's pretty cool."
