Last Saturday, the BBC One launched a new Christmas trailer that featured a clip of William Hartnell along with loads of other Christmas clips from years gone by.

Has anyone else noticed that from Sunday onward, this particular clip has been removed from the trailer, along with the sound of the Tardis?

I've seen it again a couple of times. It's probably just a shortened version you've seen, trailers usually play in varying length edits.
