The Secret Screening Room on San Francisco’s Waterfront

Hidden inside an unusual triangular building on the Embarcadero is a theater known mostly to film insiders. Robin Williams once watched his own footage here. This September, the room will host a very different cinematic experiment.

There is a stretch of San Francisco where it is almost impossible to forget that the city was built beside the water.

Walk south from the Ferry Building along the Embarcadero and the Bay follows you. The Bay Bridge rises overhead. Ferries cross the water in the distance. Runners, cyclists, commuters, and tourists move along one of the rare major streets in San Francisco that makes almost no attempt to climb a hill.

Keep walking toward Oracle Park, however, and you will eventually pass something much easier to miss.

At 600 The Embarcadero, an unusual triangular building occupies a wedge of the waterfront. There is no grand theater marquee outside. Nothing about it suggests that behind its walls is a roughly 150 seat screening room with a long connection to San Francisco’s film community.

Most people simply walk past.

Those who know it, know it as the Delancey Street Screening Room.

A Theater Without a Marquee

The screening room is part of the Delancey Street Foundation, one of San Francisco’s most unusual institutions. Founded to help people rebuild their lives after addiction, incarceration, and other serious challenges, Delancey Street operates as a self supporting residential community. Residents learn skills, work in its businesses, and help one another begin again.

The waterfront complex itself is part of that story. Delancey Street residents participated in building it.

Inside, tucked away from the activity of the Embarcadero, is a fully equipped screening room with theater seating and a small stage.

For years, it has been the kind of place that rarely appears on a tourist itinerary but circulates quietly through the film world. Private screenings have taken place here. Filmmakers have reviewed works in progress here. Industry audiences have gathered here to see movies before the rest of us. And according to Delancey Street lore, one particularly famous San Franciscan came here to watch his own work: Robin Williams.

When Robin Williams Came to Watch the Dailies

While filming Patch Adams, Williams reportedly used the Delancey Street Screening Room to watch footage from the production.

It is easy to imagine the scene. The lights go down. The projector comes on. Williams sits in the darkness watching a version of himself appear on the screen.

The film was based on a doctor who believed humor could have a place alongside medicine and that laughter could reach people during some of the most painful moments of their lives.

For Williams, the role seems especially poignant in retrospect. Few performers could produce joy as effortlessly as he appeared to. His comedy could be manic and unpredictable. A voice could suddenly become another voice. His face could transform in seconds. His entire body seemed capable of becoming part of a joke.

But today, audiences also know that the man creating all that laughter carried struggles that were largely invisible to the people watching him. That knowledge changes the image of Williams sitting inside Delancey Street.

What did he see when he watched Patch Adams?

A character?

A performance?

Or perhaps something he understood personally: the strange coexistence of joy and sorrow.

Could AI Create Robin Williams?

It is a question that would have sounded absurd only a few years ago. Today, it is becoming surprisingly literal. Artificial intelligence can generate a convincing human face. It can synthesize voices, write jokes, create dialogue, compose music, and produce increasingly sophisticated moving images. Give these systems enough examples of a performer and it is not difficult to imagine an AI recreating the recognizable surface of Robin Williams.

His voice.

His expressions.

His rhythms.

His frantic physical comedy.

Perhaps even his timing. But that raises a much more interesting question.

Could it recreate what was underneath?

Could an algorithm reproduce the performance of someone who understood sorrow yet devoted much of his life to creating joy for strangers?

There is an enormous difference between generating a smile and understanding why someone smiles.

Cinema has always lived somewhere inside that difference.

Joy Is Not the Opposite of Sorrow

We often describe emotions as opposites.

Joy or sorrow.

Love or hate.

Calm or fear.

Desire or disgust.

Human experience is rarely so orderly.

Joy can exist in the middle of grief. Love can contain anger. Serenity means something different after fear. Sometimes laughter arrives precisely when circumstances suggest that nobody should be laughing at all. Perhaps that is why the funniest people can sometimes understand sadness so well.

Robin Williams could make millions of people laugh. What audiences could not see was everything he carried into those performances. That invisible history may be part of what gives human expression its weight.

A machine can study millions of examples of sadness.

A human being can remember the day his heart was broken.

A machine can learn the visual characteristics of laughter.

A human being can remember laughing when he thought he never would again.

Are those differences important to the art we create? We may be about to find out.

An Experiment Comes to the Embarcadero

On September 26, the Delancey Street Screening Room will once again become a place for watching something unfamiliar. This time, the experiment is not a Hollywood work in progress. It is human creativity itself.

The Sparknify Human vs. AI Film Premiere is bringing films created by human filmmakers and films created using generative AI into the same theater. The filmmakers will confront the same territory cinema has explored for more than a century: human emotion. The audience will not simply be asked which film looks better or which technology is more impressive.

The question is more personal:

Which one moves you more?

One of the festival's screenings will focus specifically on Joy & Sorrow. It is difficult to imagine a more appropriate room for it. Years ago, Robin Williams reportedly sat here watching himself portray a man who tried to answer suffering with humor. This September, another audience will sit in the darkness of that same theater watching humans and machines attempt to make them laugh, ache, remember, and feel.

AI may generate the tears.

It may generate the smiles.

It may even surprise us by creating something profoundly moving.

But when the lights come back on, the question will remain:

Does a machine need to understand sorrow to create joy that feels real?

Or is feeling something machines never needed in order to make us feel it?

For one morning on the San Francisco waterfront, inside a little screening room most people walk past without noticing, we may get a little closer to the answer.
