[quote="atouchofgrace"]But was Simba really 5 years old? He was exiled 2 years (they say it on the audio commentary).[/quote]
Are you sure you remember correctly? I don't remember them mentioning how long he was exiled. I only recall them saying that the beginning of the film (Simba waking his Dad all the way to the exile scene) happens within two days.
Simba being exiled only for two years is against the biological facts about lions that they claim they studied and followed. A lion cub's tail tuft is fully formed around 7 months of age. A male's mane starts to grow around 1,5 years of age, thus Simba must've been somewhere between those ages when he was exiled. (I personally have always thought he was pretty much 1 year old exactly, just to make the maths simple.) And then... Yes, lions are fully grown at the age of three, around which Simba would've been two years into his exile - but his mane could not have been that big if he was only three years old when Nala found him. The mane is fully grown at the age of five years. And so, if he was exiled only for two years, he would've had to be three when he was exiled, and he evidently wasn't full grown back then, not even the 1,5 years old judging by him not having a head tuft.
Then there is also how male lions aren't usually capable of challenging other males until the age of five years. And I don't think Mufasa would've prefered his son to risk it, especially as he hadn't been learning fighting skills and had been eating nothing but bugs for years.
So, yes, I'm pretty sure he was five years old or even older, when Nala found him and Mufasa made him go home.
