All of the characters in the segment 'George Romero In 3D,' share names with characters in Romero's movies: Sarah, Dawn, Martin, Bub, and Cooper.
Martin mentions the movie 'Night of the Flesh Eaters', which was the original title of Romero's 'Night of the Living Dead' before he changed it to avoid potential conflict with another similarly-titled film.
In the segment 'George Romero In 3D', Bub looks and acts like Bub the Zombie in the classic George Romero film
'Day of the Dead'.
The zombie in the stockroom gets the top of it's head cut off by a rotating blade, the same way that a zombie did in Romero's movie, 'Dawn of the Dead'.
In the segment 'George Romero In 3D, Mr. Cooper (Peter New) is not only also a jerk but also looks very similar to the identically named Mr. Cooper (Karl Hardman) in the classic George Romero film Night of the Living Dead (1968). The characters also share a similar fate.
