Sally Sparrow and the Weeping Angel was the original title of the earliest script of what would become Blink. It featured miscellaneous dialogue discrepancies as well as a completely different ending to that in the final shooting script.
This script received an unexpected official release in 2020 as part of the Doctor Who: Lockdown! tweetalong of Blink, having been recovered by Steven Moffat himself.[1] It was released a few days after the tweetalong on the official Lockdown! website with a newly-written foreword by Moffat.
