Guillermo del Toro (Pan’s Labrynth, Hellboy) discusses his influences in the latest Entertainment Weekly:
For the Hellboy films del Toro goes beyond Jack Kirby-influenced Hellboy creator Mike Mignola and cites Kirby himself as the primary influence:
“Kirby’s monsters were incredibly silly--creatures with massive teeth wandering the streets popping cars in their mouths like popcorn.”
Del Toro’s favorite superhero is Len Wein and Bernie Wrightson’s Swamp Thing (which may bode well for an actual decent film adaptation that goes beyond the C-movie quality of the original films).
As a kid in Guadalajara, Mexico, Del Toro would buy the latest issues and “never complete the [bike] ride back. I would always stop half a block away and read it on the sidewalk.”
