Dr Smith in his debut, on the Nostalgia Critic's Lost in Space review.

~ Dr. Smith

Dr. Smith is a minor but recurring villain on the Nostalgia Critic webseries.


Dr Smith is a peculiar human/spider hybrid based on Gary Oldman's performance as the character of the same name from Lost in Space. Smith is an even hammier version of said character (if that is even possible) who, on top of employing them as minions and resembling one himself, is utterly obsessed with spiders, convinced that they are the scariest thing in the world. In an ill-fated attempt to scare the Critic, he often waves his hand spookily at the camera while emphatically repeating some variations "SPIIIIDERS! A GIANT LEGION OF SPIIIIDERS!".

Dr Smith appears out of a floating, golden time portal (an allusion to the original film's time travel shenanigans) to the Critic, interrupting his reviews to defend the scariness of “SPIIIIDERS”. The Critic invariably gets more and more annoyed before eventually resorting to shooting at Smith with a gun. While the shots do not seem to affect him (it is difficult to say whether he is immune to bullets, if he is protected by the time-portal, or if the Critic simply misses him every time), they upset enough that he prompty retreats off-screen before the Time Portal vanishes.

The only appearance of Dr. Smith that broke this mold showed him as the "creative consultant" of Dr. Insano while he was writing the script for The Secret of NIMH II: Timmy to the Rescue, in the eponymous review. Warmly approving of Dr. Insano's plot twist (Martin Brisby turning into a mad scientist), Dr. Smith engages in evil cackling with Insano, revealing that his "evil laugh" is actually quite harmless-sounding.

Physical Appearance

Dr Smith is dressed in a a Palpatine-style black robe; his face is dark and bluish and he has large skeletal hands. It is assumed the rest of his body resembles the many-legged creature of the original Lost in Space movie, but all shots of him are cut at the waist.


  • He was portrayed by Doug Walker.
  • The character seems aware of the movie while simulataneously referring to his movie counterpart's behavior as if it were really his own past actions — a fourth-wall tomfoolery that is shared by many of the Nostalgia Critic's parody character.
