Okay, so, here's a completely original idea for a sci-fi/fantasy action adventure movie.
Bear with me here, it's totally original.
In the prologue, General Villain breaks out of the whatever prison. He was imprisoned by the previous Chosen One.
He summons his comic-relief henchman/thing and his bad guy army. They begin their war with the good guys.
Then, we cut to this person. They're probably a white, heterosexual male, younger than 40 and older than 10.
He's an average guy with an average life, who is single and attractive.
Anyway, he encounters some bad guys and a band of good guys. There is a fight, and the hero tries his best to survive. The good guys win/escape, and he goes with them. He learns from a wise mentor that not only is he a Special Person like the rest of them, but he is also the Chosen One, who will save everybody according to The Prophecy. He is a Special Person because one of his parents was a Special Person. Said parent ditched him after he was born
