The Mall of America will become the Upside Down this Sunday as it hosts a "Stranger Things" star ahead of the hit show's return to Netflix.
David Harbour, who plays Chief Jim Hopper in the '80s-set sci-fi romp, will be at a free-to-attend Q&A session in the Rotunda of the Bloomington megamall on Sunday afternoon.
What's more, he'll also be in attendance at a private after-party at the Hard Rock Cafe that is open only to some "Stranger Things" fans.
So how do you get in? By dressing up as your favorite "Stranger Things" character for a costume contest that will be held before Harbour's Q&A.
Entries for the costume contests will be taken between 1 and 2 p.m. Sunday in the Rotunda, followed by judging starting at 2 p.m. The Q&A then happens at 3 p.m. before final judging at 3:30 p.m.
The new series of "Stranger Things" is being released on July 4 and will be set in Hawkins, Indiana in 1985.
According to the synopsis, it's set during the summer when the town is "threatened by enemies old and new."
