It was practically impossible not to fall for David Harbour and Millie Bobby Brown as Stranger Things' unlikely father-daughter dream team. Jim Hopper began as a gruff police chief taking in a traumatized Eleven, but their bickering, protectiveness, and wonderfully mismatched grumpy-sunshine energy turned them into one of Hawkins' most beloved relationships.

And apparently, the heart wants what it wants, because David Harbour and Millie Bobby Brown are set to star side by side again, with Harbour excited to recreate their father-daughter dynamic.

The father-daughter dynamic between David Harbour and Millie Bobby Brown is getting a rather grown-up makeover. Speaking to Variety on the Emmys red carpet about their secret Netflix action project in development, Harbour revealed that the new story will explore him fathering a daughter in her 20s, rather than navigating the teenage years they tackled in Stranger Things. And this time, she is an FBI agent.

“We do have this father-daughter dynamic that I think we play very well,” David Harbour said, explaining that Stranger Things allowed the pair to explore the messy business of raising a teenager, from rebellious streaks to Hopper learning how to be a parent. Their new project, however, moves the relationship into decidedly more complicated territory, with both characters facing their own troubles.

Harbour’s conversation with Variety has offered a glimpse into the otherwise tightly guarded project, which follows a disgraced FBI agent turned security expert forced back into action when his estranged daughter vanishes on a mission. With Millie Bobby Brown playing the daughter and fellow FBI agent, their familiar bond is heading somewhere considerably more dangerous than Hawkins.

But fans may not have to wait very long, as David Harbour has also revealed exactly where the script currently stands for this original and unique project.

David Harbour offered another peek behind the curtain on the very same Emmys carpet, this time revealing to E! News how far the secretive project has progressed. The actor shared that the team already has two scripts in hand, and he sounded particularly pleased with how the unexpected story has taken shape so far. He also made it clear that there is plenty to be excited about.

Harbour and Millie Bobby Brown have been intent on taking the ingredients that made their Stranger Things chemistry work and cooking up something entirely original. Their new story is being shaped by writer Jack Thorne, whom Harbour praised as a brilliant writer capable of balancing emotional depth with wild action. With two scripts already delivered, the reunion is looking increasingly real, and fans could soon see their beloved father-daughter dynamic enter a very different chapter.
