At one point, Winona Ryder’s Joyce chases away David Harbour’s Hopper, who is on his way to fight the prison Demogorgon. She asks him to be careful in his mission, noting that she doesn’t want to give him a second funeral. At that moment, they share a tender kiss. “This kiss was not scripted,” said a tweet from the Stranger Things writers’ account. “Winona and David added it on the day of the shoot.” This kiss was not scripted, Winona and David added it on the day of filming pic.twitter.com/9vSWwYliWU — strangerwriters (@strangerwriters) July 2, 2022 Another post indicated that the moment between Eddie (played by Joseph Quinn) saying, “I love you, man” to Dustin (played by Geten Matarazzo) was not planned. “‘I love you, man’ was improvised by Joe,” the writers revealed. “I love you, man” was improvised by Joe pic.twitter.com/z5gYyl18KF — strangerwriters (@strangerwriters) July 2, 2022 And finally, the moment when Lucas – as Jason beats him – pleads, “Erica, help” was improvised by the actor himself, Caleb McLaughlin. “Erica, help” was improvised by Caleb. pic.twitter.com/9g5etO5VAz — strangerwriters (@strangerwriters) July 2, 2022 That kind of collaboration isn’t uncommon on the set of the series created by Matt and Ross Duffer according to Sadie Sink — who plays Max — even with the younger cast members. She described her experience to Deadline this week. “What all the kids have loved about the Duffers is that they’ve never treated us any differently than they would an adult cast member,” Sink said. “Like, they really respected and valued our opinions and created a really fun environment. They never undermined us in any way and really just listened and worked with us.”
