Have you ever thought you were losing your sanity? Have other people ever wondered if you were losing your mind? Have you ever been in a toxic relationship that led you to take desperate measures?

Cecelia Kass (Elizabeth Moss) answers yes to all three questions in the highly entertaining suspense thriller The Invisible Man.

In the film’s terrific opening sequence, Cecelia executes an escape from her abusive husband Adrian (Oliver Jackson-Cohen) with help from her sister Emily (Harriet Dyer).

Two weeks later, after taking refuge at the home of her friend James (Aldis Hodge), Cecelia is informed that her husband has died by suicide. Her husband’s attorney Tom (Michael Dorman), who is also her husband’s brother, informs her that a generous inheritance will come her way.

Soon after, weird things begin occurring in Cecelia’s life that lead her to question her own sanity. When she shares her suspicions about what is happening, others are dubious about her claims.

Revealing more about this setup and the story that follows might include spoilers or near spoilers. It is okay, I think, to mention that the film is likely to keep you guessing about what’s going to happen next and what will be the ultimate resolution. That pretty much defines suspense, does it not?

But a few words about the production shouldn’t spoil anything. The film’s writer/director Leigh Whannell, co-creator of the Saw movie series, uses shots of doors and hallways effectively to create subjective views of places where trouble may lurk. His use of shadows and low light situations adds to the creepiness. The sound design featuring loud, low-pitched ominous notes creates just as much tension as the violin-dominated Psycho soundtrack did sixty years ago.

The modern house that Cecelia and Adrian share is large and spectacular and provides a great setting for the film’s opening shots. It’s even cooler than the Park family’s home in Parasite.

Big applause is due for the performance of Elizabeth Moss. Her character refers to herself as “just a suburban girl” who met her husband at a party. But she is resilient and tough. Moss can play gorgeous and also rugged (as in, no makeup and dirty hair) in the same film and do both believably.

The Invisible Man is rated R because of blood, gore and violence. Tread lightly on the interwebs before you see it… spoilers are likely to abound.
