Fans are eagerly anticipating the second season of Netflix's summer hit "Stranger Things," which some of the stars and producers of the sci-fi drama tease will be much bigger and, yes, much darker.

Speaking with journalists at the the annual BAFTA Awards Season Tea Party, executive producer Shawn Levy said the stakes will be raised in Season Two, set for release later this year.

“The threat, which in Season One was to Will Byers, has grown. That’s all I’m going to say!" he teased. "But, I will say Season Two has a bigger cast and is definitely loyal to the kind of magical storytelling that we established in the first season. It’s character-based and still about our core group of characters.”

Most of the Season One cast, including Winona Ryder and Millie Bobby Brown, will return, joined by the likes of Sean Astin (“The Lord of the Rings”) and Paul Reiser ("Mad About You”). According to Noah Schnapp, who plays Will Byers, we’ll see much more of his character in Season Two. “In the last episode, I threw up a slug, so Season Two begins with what happens from there," he said. "There may have been some effect on him. I may or may not have turned into a monster. You’ll have to watch to find out.”

Finn Wolfhard, who plays Mike Wheeler, teased the second season might expand on the group of youngsters in terms of character growth. “Now that we’ve done a season, we know exactly about our characters. We are very conscious of them and can take them to the next level,” he said. “I think we’ve grown up a little bit, and our characters have too. They have been through a lot and have used those experiences to help them grow and to be stronger in Season Two.”

Filming of "Stranger Things" Season Two is already under way in Atlanta.
