Can't remember a movie name
 

Some visier uses his magik in order to steal the throne from a prince and the prince goes on a long quest to find the place where the sorceror visier hid his heart.
He allies himself with a thief.
There are many special effects, like giant birds.
At the end he throws the heart on the floor at the visier's feet, the heart breaks into pieces and the visier's face starts cracking until he explodes.
