It’s clear from the start of “The Housemaid” that all is not well in the home of Nina Winchester (Amanda Seyfried), where Millie Calloway (Sydney Sweeney) is interviewing for a job. It’s one of those far-too-large homes in which no inhabitant could possibly be happy; what remains to be seen is the flavor of their unhappiness.

Sure, Sydney Sweeney gets to be "The Housemaid," but it's Amanda Seyfried who's unleashed in the twisty thriller based on the Freida McFadden book.

“The Housemaid” is Paul Feig’s delicious, satirical look at the secret depravity of the ultra-rich, but it’s so well constructed that’s it’s not clear who’s naughty or nice. Halfway through, the movie zigs and everything you expected zags.

Director Paul Feig’s erotic crime thriller plays off silly sexual stereotypes like the naughty maid, and then flips them on their head.

Paul Feig paid tribute to his fellow director, Rob Reiner, on Monday night by dedicating the premiere screening of his new movie "The Housemaid" to him.

The twisty thriller follows Millie (played by Sydney Sweeney ), a young woman with a troubled past who is hired as a live-in housemaid for a wealthy couple, Nina ( Amanda Seyfried) and Andrew Winchester ( Brandon Sklenar ), as it’s quickly revealed that things aren’t as perfect as they seem.

Sklenar, 35, has opened up about his difficult childhood, revealing how he was "shuttled" between homes after his parents divorced.
