A peek inside the psychological thriller 'The Invitation'

[...] things get even more unsettling as the evening goes on, between the serene calm of Eden and her new partner David (Michiel Huisman) talking about spiritual journeys, and a few weirdos who no one really knows.

Screenwriter and producer Phil Hay noted that he and his co-writer Matt Manfredi wanted to explore the true nightmare of what it would be like to be completely alienated from someone you loved.

[...] as with any interaction with old friends or lovers, there is always going to be an unknown element — especially when you toss in the eccentric, searching personalities that Los Angeles attracts.

There's something really dark behind that because it doesn't always play out the way you expect it to and people can take advantage of that and a lot of that has played out in the hills before.

The threat, or promise, of new age religions and cults in particular ignites the imagination of some of the party guests as they wonder what Eden's intentions are.

Kusama, who filmed the entire movie in a real house off of Mulholland Drive for a tiny $1 million budget, hopes ultimately that audiences are open to the mystery of "The Invitation."
