How a TV show gets made, from pitch to first episode
From pitch and pilot to writers' room, filming and delivery, here is the chain of decisions that turns an idea into a finished television episode.
A television series reaches your screen through a long chain of decisions: an idea, a pitch, a script, a commitment of money, and then months of writing and filming before a single episode is finished. Knowing the chain explains why shows take so long to arrive and why so many ideas never do.
Development: the idea and the pitch
Most shows start as a written pitch. A creator or producer brings a short document, and often a sample script, to a network, a streaming service or an independent studio. The buyer is weighing a promise: is the idea distinctive, who is it for, and can it carry more than one season?
The decision: pilot and green light
Sometimes the buyer orders a pilot, a single episode made to test the idea on screen. Sometimes the script alone is enough and the show is ordered straight to series. A green light is a commitment to make a set number of episodes on a schedule and a budget, which is why it is the hardest step to reach and the easiest to lose.
Writers' room and pre-production
With a showrunner in place, a writing team breaks the season into episodes and drafts scripts. Pre-production follows: casting, locations, sets, costumes, and a shooting schedule built around the availability of cast and crew. Unions such as the Writers Guild of America, the Directors Guild of America and the Producers Guild of America negotiate the minimum terms their members work under, so the rules of a production are largely agreed long before the cameras roll.
Production and post-production
Filming is usually the shortest phase. Episodes are often shot out of order, scene by scene, so that locations can be grouped. Post-production then begins: editing, visual effects, sound design, music and colour. The finished cut goes back to the buyer for notes, and changes at this stage are normal rather than a sign that something is wrong.
From delivery to your screen
Delivery, marketing, subtitling and classification all sit between the locked cut and the release date, and a renewal decision usually depends on how the first season performs.
Bodies such as the bfi.org.uk, the dga.org and the producersguild.org publish guides and agreements that explain these stages in more depth.
The bottom line: a series is the end of a chain of choices, so patience with the process is more useful than impatience with the calendar.
