Passage: Each film had the benefit of a full year of post-production time before its respective December release, often finishing in October–November, with the crew immediately going to work on the next film. In this period's later part, Jackson would move to London to supervise the scoring and continue editing, while having a computer feed for discussions to The Dorchester Hotel, and a "fat pipe" of Internet connections from Pinewood Studios to look at the special effects. He had a video link and 5.1 surround sound to organise meetings, and listen to new music and sound effects generally wherever he was. The extended editions also had a tight schedule at the start of each year to complete special effects and music.

Question: When are films generally released?
December
