Keep an eye on your mirrors — and maybe your Comic-Con schedule — because the upcoming film Witchboard appears to be conjuring up something spooky in San Diego. The upcoming horror film, which hits theatres on August 15, dropped an Instagram hint seeming to confirm some sort of appearance:

Directed by Chuck Russell (The Mask, A Nightmare on Elm Street 3), Witchboard is a reimagining of the 1986 cult classic. The film stars Madison Iseman (Jumanji), Jamie Campbell Bower (Stranger Things), and Aaron Dominguez (Only Murders in the Building). This new take follows a young couple who stumble across an ancient pendulum board and unwittingly invite a malevolent spirit into their lives.

There’s no guarantee this will be a panel — it could be anything from a street team to something else. But something witchy definitely appears to be manifesting.
