Directed by Jake Kasdan – Starring Bill Pullman, Ben Stiller, Kim Dickens, Ryan O’Neal

An eccentric private detective is pulled into a blackmail case that slowly forces him out of the isolated world he’s built around himself.

Zero Effect is a pretty effective modern update of a noir detective story, built around a really strong performance from Bill Pullman and an early-career Ben Stiller showing he could do more than broad comedy.

Stiller actually works best here as the straight man. Most of the humor comes from how exhausted and bewildered he is trying to manage Pullman’s increasingly eccentric detective.

The supporting cast is strong as well. Kim Dickens is great as a subversion of the classic femme fatale, and Ryan O’Neal brings desperation to the wealthy businessman caught up in the blackmail scheme.

What I like most about the movie is that the mystery itself almost becomes secondary.

The case is good, and watching Zero work through it is fun, but the real story is about a man who has completely isolated himself suddenly becoming emotionally invested in another person.

Zero is introduced as this brilliant but deeply detached recluse who avoids his clients, pushes people away, and treats human interaction like a burden.

But through this case — and especially through his connection with Gloria — we slowly start to understand why he is the way he is.

There’s a sadness underneath the character that Pullman plays really well. The movie gradually reveals someone who has spent so much time observing people that he no longer knows how to participate in life himself. At first, that detachment feels like a strength — even the reason he’s such a brilliant detective — but the holes in that facade grow larger as the film goes on.

That’s what gives the ending its emotional weight.

It’s tragic in some ways, but also oddly hopeful.

The relationship at the center of the story may not work out, but the experience changes Zero in a way that feels meaningful.

I would have loved a whole series of these. The character is strong enough to support it, and the dynamic between Pullman and Stiller is fun enough that I could easily imagine a decade of strange little mysteries built around them.

I don’t think the movie was especially successful when it came out, and it’s mostly faded into the background over time, but I’ve always liked it.

It’s funny, melancholy, a little weird, and much more heartfelt than it first appears.

Verdict: Engaging
