Columbia released this film featuring the Spider, whom Stan Lee cited as an inspiration for Spider-Man (especially due to the web-pattern imprinted cloak that the Spider wears in this film). Decades later Columbia released a Spider-Man film, and then a sequel to that film, where yet again a spider-themed protagonist fought an opponent named Octopus (also, in one of the Spider novels he fought an opponent called the Iron Man; Lee also created Iron Man).
