Mufasa, Scar from 'The Lion King' weren't actually brothers

"The Lion King" producer Don Hahn said there was more than a possibility that two leo siblings, Mufasa and Scar were not really related to each other.
The 55-year-old producer said according to lions' mating habits, it was possible the two did not belong to the same family, reported DigitalSpy.
"(Scar and Mufasa) would not have both the same parents. The way lions operate in the wild... When the male lion gets old, another rogue lion comes and kills the head of the pride.
"One lion will always kind of be off in the shadows...So we sort of figured Scar and Mufasa couldn't really be from the same gene pool," Hahn told HelloGiggles in an interview.

Hahn also recalled Scar's dialogue from the 1994 double Academy Award-winning animated feature that made the theory believable.
"In fact, that's what (Scar) says. There's a line, he goes, 'I'm from the shallow end of the gene pool' when he's talking to Mufasa," he added.
