Here are the newest stars of 'Stranger Things' who have joined for season 2

Several new faces are joining Netflix's hit "Stranger Things" for its second season.

A few of the actors you'll probably recognize - especially if you were a fan of the '90s sitcom "Mad About You" or the "Lord of the Rings" movies. Others you'll probably meet for the first time on the show's sophomore season.

But what we're most sure about is that the show's creators and writers, brothers Matt and Ross Duffer, will deliver another thrilling, blast-from-the-past, sci-fi adventure.

All the actors whose characters survived last season are expected to return. (And Millie Bobby Brown will reportedly reprise her role as Eleven.) The series is set to return in 2017.

So while you're waiting, why not get acquainted to the new kids on the block?
