The Greatest American Hero

The Shock Will Kill You - S2-E13

Continuity mistake: After Ralph drops down into the tunnel in order to lure the creature, Ralph stops in front of a junction box on the wall. In the shot facing the box head-on as Ralph gets one of his holographs, suddenly there's writing on the cover of the junction box. The writing is not part of Ralph's vision. (00:37:55)

Super Grover

Reseda Rose - S1-E6

Continuity mistake: When Ralph is flying to Simpsons house, he continuously flies over the same area 5 to 6 times...meaning it is just reused footage. (00:20:50 - 00:21:40)
