Stranger Things Chapter Six: The Spy (2016– ) watch online HD

This is the first episode not to feature Eleven, and the first time one of the main cast is listed as credit only.

The motion detector beeping sound is the same as that in Aliens - Le retour (1986).

The series is well known to draw influence from Stephen King's books and movies. The song playing over breakfast with Nancy (Natalia Dyer), Jonathan (Charlie Heaton) and Murray (Brett Gelman) is "Blue Bayou" by Roy Orbison. This song heavily features in the book/movie Dreamcatcher, l'attrape-rêves (2003) by Stephen King, a story about a group of kids who make friends with a supernatural, psychic boy ego helps them fight aliens and work against a government agency, trying to keep it under wraps.

The scene where Dustin (Gaten Matarazzo) and Steve (Joe Keery) are throwing meat on to the railway line, is reminiscent of scenes in both Les dents de la mer (1975), and Stand by me - Compte sur moi (1986).

Both Winona Ryder and Paul Reiser have been involved in the Aliens franchise. Paul (Aliens - Le retour (1986)), Winona (Alien, la résurrection (1997)).

The scene where Joyce yells at the doctors about not know what's wrong with Will shares a strong similarity to a scene in The Exorcist (1974) where Ellen Burstyn berates doctors for not knowing what's wrong with her daughter Reagan.

When the leader of the assault team says, "Stay frosty, boys", it is an homage to Aliens - Le retour (1986) where Michael Biehn's character Hicks says the same thing when entering the facility with his assault team. Another quote reminiscent from Aliens that can be heard is "I don't see sh#t, man". In both instances, the teams are ambushed and massacred in the end.

The scene where the research facility is monitoring their soldiers via radar tracking devices in the tunnels of the upside down is reminiscent of (and quite possibly an homage to) the scene in Aliens - Le retour (1986) where the marines enter the alien nest. Both scenes featured actor Paul Reiser watching the process through a monitor.

When Steve (Joe Keery, Lucas (Caleb McLaughlin), Dustin (Gaten Matarazzo) and Max (Madmax) (Sadie Sink) set a trap for Dart in the old junkyard, they use steel mesh and iron sheets to add protective armour to the bus, a reference to the armoured bus used in the second Mad Max film (Mad Max 2: le défi (1981)) as a gate to the petrol refinery Mad Max is helping to defend.

When the fog moves in on the soldiers in the tunnel prior to the arrival of the "demodogs", a sinister laugh can be heard. It's heard again as Hopper (David Harbour) looks down at the tunnel opening.

The scene where Nancy (Natalia Dyer) and Jonathan (Charlie Heaton) are in their separate rooms, hesitating about getting together, very clearly evokes a similar scene between Indy and Willie from Indiana Jones et le temple maudit (1984).

When Bob (Sean Astin) looks at the map he asks if X marks a treasure. Sean was in Les goonies (1985) looking for a treasure where X marked the spot.
