My Blackbeard would've had a sewed up neck...showing that he got his head chopped off, and sewed it back on.
His introduction would've been the same...except when he says "HANG!" he actually means it...and the entire crew of mutianeers(sp?) gets HUNG by the neck, and killed. Except Jack. Because he knows where the Fountain is.
His powers would've been explained by showing his skill in the voodoo magic, and he would've told this to Jack in his cabin.
He would've also stated he is a collector of mystical relics. His most prized posession is the Sword of Triton...which allows him to power the ship.
I would've shown Barbossa's flash back. He would've been tied up by the leg...and Blackbeard would've given Barbossa a choice. Live, by cutting off your own leg, or die. Showing that this guy is evil. More evil, and vicious then Jones.
We can throw in the Angelica redemption angle. That could've worked, had he been this evil.
Anyhoo....we give Barbossa and Teach a grand 10 minute battle, while Jack fights Angelica...for something.
Barbossa finally corners Teach, and stabs him. Over. And over. And over. And over. And over....all while saying....
"There be 25 men on me ship when ye sunk it..."
Blackbeard begins to fall....
"This one be for me leg...."
And decapitates him. It can be off screen. Or something.
Angelica should get shot during a cross fire...and Jack attempts to save her. But she's a stupid *****, so she shoots Jack, which forces him to drink the fountain with her.
Oh yes...Jack Sparrow is willing to sacrifice his life for another....because in my flick, they would be better developed.
Jack puts the tear in one, and all that jazz....Angelica pulls a Blackbeard, and turns out to be a ***** in the end.
Jack Sparrow laughs....he switched them. Tricked her....he lives, she dies. Jack is back!
