The animal subject the BBC really really wants to bag, the Holy Grail of the BBC wildlife documentary team occurs around our waters apparently, but is too dangerous and too illusive to film. It never featured in the Blue Planet, despite being marine, and is the largest predatory invertebrate in the world - I give you the Giant Squid (or Collossal Squid - they'd take that too). Would be a stunning ....if very brief film!
Of course, I'd also like a thylacine film... and so prove it's continued existance.
