here's a paragraph from an obituary of the Economist.I'm really confused about the meaning of the "film". Does it mean cover or ban? And does "interjections" mean interruption here?
Each leader, from more open-minded Deng Xiaoping onwards, was battered with his opinions and demands. They were drafted in his centre of operations, a study in which it was impossible to cram any more books, and from which he angrily shooed away anyone who filmed what he was writing. Sometimes they took the form of open letters, sometimes interjections at Communist Party congresses.
Many thanks for your answers!
