Dungeons & Dragons played in 'E.T.: The Extra-Terrestrial' (1982)

According to the trivia at IMDB:

"In the movie 'E.T.: The Extra-Terrestrial' (1982), Elliot's older brother Michael and his friends are shown playing Dungeons & Dragons at the beginning. Director Steven Spielberg, a fan of the game, played it when it first came out in 1974.

"According to an interview with Robert MacNaughton (Michael) on Yahoo Movies, MacNaughton explained that the original ending involved a game of Dungeons & Dragons: 'The last scene in the movie wasn't supposed to be the scene that ends up in the movie. The last scene was going to be all of us playing Dungeons & Dragons again, except this time, Elliott's the dungeon master. Because he was the one that found ET, he sort of got in with the group. And so that was supposed to be the final scene, it was in the script and everything, and then they would pan up to the roof and you'd see the communicator and it's still working--in other words, Elliott is still in touch with E.T.. But after they did the score, the music, and they saw what they had with the spaceship taking off and everything [laughs]--how can you follow that? I mean, it was a wise choice.'"

No doubt this was the inspiration for using D&D as the framing story in "Stranger Things," set in 1983.
