The rooftop scene, where Clark super-speeds onto the path of bullets that would kill Lois and Oliver, is a nod to the scene in the movie, with a nice twist in the end.
The "Good Morning, Metropolis" cardboard marketing stand of life-size Lois and Clark features them in the same positions as the movie's poster. After a chuckle though, one may find it troubling that Lois is filling the place of the movie's prostitute, especially as the poster has been spoofed in adult entertainment as well.
