The New Year 2021 episode of Doctor Who opens with a nod to another famous scifi franchise.
A reference to Aliens occurs shortly afterwards.
Starting near 35:50, there is a whole scene which is a better follow up to Aliens than Alien 3.
Are there other scifi references in this episode of Doctor Who? Have there been any interviews with cast or crew that confirm them?
Three other candidates (in decreasing order of certainty):
The idiot Prime Minister introducing the Daleks as 'defence drones' (multiple scences, starting at 33:40) is strongly reminiscent of Omni Consumer Products and their 'Enforcement Droid 209' in Robocop.
The Doctor's plan to use the 'spare' Tardis to destroy the 'Death Squad' Daleks reminded me of Apollo sacrificing the Pegasus in the two part Battlestar Galactica episode 'Exodus'. Admittedly, this is highly tenuous, and my memory may be shaky - I haven't watched the Galactica remake since it first aired.
The manner in which the Dalek creature takes over Leo Rugazzi (21:40) struck me as a reference to the Drakh Keeper in Babylon 5. However, the same thing has happened in Doctor Who before, so I suppose this doesn't really count.
