Is the omnibus an all new edit or a remastering? I seem to recall there being one before. My local PBS station would run an entire story in one afternoon when I was a kid.
And thanks for the heads up! Hopefully this won’t be scuttled for a technical snafu like the screening of the animated Power Of The Daleks I attended.
On disc, the omnibus versions are always direct preservations of the broadcast tapes. And yes this is an old edit. But for the theatrical showing they’re in the process of reconforming the edit using the newly restored video and 5.1 mix.
