There are smart people here, right?
I was watching an old episode of a TV show called The Hotel Inspector, which for those who don't know is basically a makeover show for failing hotels and accommodation businesses. One guy in particular had cluttered up his hotel with a strange collection of memorabilia, which included a Dalek. When the trailer was shown, the Dalek could be clearly seen - but in the episode itself they'd used ... I don't know, an anonymity filter or something; scrambled the picture so you couldn't see it, anyway, although they referred to it clearly as a Dalek. This was shown on a UK TV station (Channel 5) which is a competitor of the BBC.

So my question is ... does the BBC, or some other organisation, have such strong image rights on Daleks that nobody else can ever show them even incidentally? And would this work for all such images? For example if you had your picture taken with a Dalek in 1965, would the Dalek's identity have to be erased before you could show that picture on TV?

If anyone can shed any light on this I would very much appreciate it!
