If 3pp stuff is an option, the Pyromancer is one of my favorites. 9th level caster, gets Charisma (their casting stat) to damage with fire spells, a short 2 feat tree to get double Charisma mod to damage, able to eventually bypass resistance and immunity (around 15th or so I think. I dont think its their capstone) Plenty of flame spells to set the world alight with.
Note: Know nothing about the book or movie, so cant guarantee the concept fits.
