What are some other movies similar to The Guest (2014)?
When you say ‘similar' do you mean aesthetically or narratively?
If the former The Guest was heavily influenced by John Carpenter so you should seek out things like:
Escape From New York
Assault On Precinct 19
If it's a narrative similarity you're looking for then you want things a little nihilistic but with a bit of a exploitation edge to it. Things like:
Essentially The Guest is very Neo-Noir so you should find films like:
To Live And Die In LA
The Last Seduction
The Lost Highway
No Country For Old Men
The Friends Of Eddie Coyle
Hope that helps and covers any angle you were after.
A soldier introduces himself to the Peterson family, claiming to be a friend of their son who died in action. After the young man is welcomed into their home, a series of accidental deaths seem to be connected to his presence.
