1. A door, comprising: a. a peripheral frame;b. first and second door skins secured to opposite sides of the frame, each of said door skins having an exterior surface and an interior surface and each of the door skins having a plurality of molded panels; andc. a double backbone core component disposed between the interior surfaces of said door skins, wherein the double backbone core comprises two backbones with expandable cells extending parallel to each other along a length dimension of the frame, wherein each of the backbones extends the length of the frame, and extends between and directly engages opposed interior surfaces of the panels to support a different molded panel of the first and second door skins wherein each of said door skins has a plurality of molded panels arrayed in two longitudinally extending columns, and each of said backbones is positioned between a middle of one of said columns of panels and an outer edge of the same column of panels. 2. The door of claim 1, wherein the core component is formed from a plurality of interconnected strips, each strip is made of cardboard or paperboard. 3. The door of claim 1, wherein the core component further comprises connective portions connecting the backbones, and has cells of a first size forming the connective portions and cells of a second, smaller size forming the backbones. 4. The door of claim 1, wherein the core component is adhesively secured to spaced rails forming said frame. 5. The door of claim 2, wherein said strips are of a uniform thickness, the uniform thickness of the strips being defined by spaced parallel edges of associated strips. 6. A door, comprising: a frame including a pair of stile members extending parallel to each other, an upper rail member and a lower rail member, wherein the upper rail member and the lower rail member are disposed in parallel to each other and are coupled between the pair of stile members;at least two door skins attached to said frame, each of the door skins having first molded panels laterally spaced from second molded panels; anda structural void filler disposed within said frame, wherein said structural void filler comprises a first backbone, a second backbone, and a connective cellular core interconnecting the first and second backbones, wherein the first and second backbones have higher fill density than the connective cellular core, the first and second backbones extending the length of the frame and extending between and directly engaged with inner surfaces of the opposed door skins, and the first backbone is positioned to support opposed first molded panels of the door skins, and the second backbone is positioned to support opposed second molded panels of the door skins,wherein the first backbone is located between a middle of the first molded panels and an outer edge of the first molded panels, and the second backbone is located between a middle of the second molded panels and an outer edge of the second molded panels wherein the first molded panels are laterally spaced from the second molded panels on each door skin. 7. The door of claim 6, wherein a portion of the connective cellular core is disposed between the first backbone and the second backbone. 8. The door of claim 6, wherein the first backbone and the second backbone each comprise a plurality of cells having a first area and the connective cellular core comprises a plurality of cells having a second area greater than the first area. 9. The door of claim 6, wherein the structural void filler further comprises a portion of the connective cellular core disposed between the first backbone core and one of the stile members and a portion of the connective cellular core disposed between the second backbone core and the other of the stile members. 10. The door of claim 6, wherein the structural void filler is formed from a plurality of interconnected strips, each of the strips formed from a member selected from the group consisting of cardboard and paperboard. 11. The door of claim 10, wherein each of, said strips is formed from the same material as the other strips. 12. The door of claim 11, wherein each of said strips has a common thickness, the common thickness of each strip being defined by the distance between spaced parallel edges of each strip. 13. The door of claim 12, wherein the thickness is at least equal to the thickness of said frame. 14. The door of claim 13, wherein each of the first and second molded panels are arrayed in two longitudinally extending columns, respectively. 15. The door of claim 14, Wherein each of said strips has a plurality of slits extending therethrough, said strips being interconnected at the slits.
