How many revisions does a script usually go through for you? And is it different based on what show you're working on - do the Who folks have a different process than the Halcyon team, for example?
The drafting process is pretty much the same on all UK dramas but the number of drafts differs every time. The treatment usually goes through a bunch of revisions, and then a script can go through any number of drafts. Then there are usually amendments to the script once it has been issued for shooting. Face the Raven had about nine or ten drafts, Thin Ice only had five. My episode of The Halcyon had seven.
But actually those figures are a lie because I go through about three drafts myself before I hand in a “first draft” to the production. I do a zero draft just for me that no one else ever sees, then a draft that my BFF reads, then a polish that becomes my official “first draft”.
