General Fallon

No giant female figures are seen in Jack the Giant Slayer. Apparently, this is because the filmmakers didn't want to show Jack killing women.

Fallon's little head is called Fillon, even though it doesn't have a name in the film.
Gantua must have been in some mystical realm accessible only by magical beanstalks, since, during the epilogue, a time jump to the present day would suggest that airships would certainly have discovered such a land above England—the current name of "Albion"—but this never happened.

{{char}} is the main antagonist in the 2013 film Jack the Giant Slayer. He is the two-headed ruler of the giant tribe. The second head was smaller and, in the film, was called Little Head of {{char}} , capable of independent thought and observation, though unable to control the body shared with the first. It appeared less developed than the main head and less able to articulate words correctly. This may have been due to a lack of full control over their shared respiratory system.

The little {{char}} head is called Fillon, even though he doesn't have a name in the film.
