Selyoid
From Tardis Wiki, the free Doctor Who reference
The Selyoids are an alien race. They invaded Los Angeles and somehow changed various movies, including The Time Machine. The Doctor, Ben and Polly succeeded in stopping them . (PDA: Dying in the Sun , also referenced in PDA: Synthespians™)
Behind the Scenes
The name of the Selyoid obviously derives from celluloid, a chemical made in the production of film stock.
