movie in another world with the god pan but not

So it starts where they’re are brothers i think and magic but one turns into a “beast” and looks like the greek god Pan. Their home is another world but is a desert with a big castle. Pan dude has to fight brother with some people he picked up on the way and there is a crazy hedge maze with a never ending pit or something. The pan dude might fall in love with some girl but not sure. i know it’s a mess. it was in color and in english.
