Don’t tell Netflix –David Harbor spills secrets of strange things!

The actor who plays Jim Hopper in the hit series has been called out by his co-star Millie Bobby Brown During a brief hiatus from filming the upcoming fourth season of the series, David decided to go online to speak to fans, but forgot that he was still wearing his character’s costume and bloody makeup.

“What’s the matter everyone? How are you?” David, 45, started. “I haven’t done Instagram Live in a while. I think I can only be here for three and a half minutes because I think I have to get to the set pretty soon.”

“I’m here doing the fourth season of our TV show,” he continued. “I don’t think I should show you these things. Who wants to hear spoilers for season four? Just let me read straight from the script.”

Despite the joke, David didn’t give fans any script details – but his character’s dusty fur and facial scratches are an indication that Hopper will be into a difficult fourth season.
