For starters, the haircut needs sorting.
But most important of all is the flying take offs and landing scenes.
Superman Returns with all its cgi and technology advancements was a disgrace in terms of the flying take offs and landing scenes of Superman.
Compare any of the landings and take offs to Superman 3, and the entire crew of Superman Returns should have been embarrased.
I rewatched Superman 3, and was simply astounded at the quality of the way Superman takes off and flys into the air, all done in real time, and using Chris Reeve himself in all the scenes.
I would particularly point you to the landing scenes in the Chemical fire scenes,
the amazing take off when Superman goes out of the bar drunk.
Without a doubt, that flying take off when superman comes out of the bar and is totally drunk, is simply a work of art, and whoever arranged that needs an award!
The new Superman movie has to have similar or better landings and take offs.
We will not accept cheap cgi attempts that are so crap and boring.
The take offs in superman 3 are nothing short of incredible and look amazingly realistic.
Not only are they so gracefully done, they are mind boggling how they achieved them using no cgi. quite remarkable.
I just wish whoever takes charge of the flying scenes sits down and watches Superman 3 and Superman The movie before even attempting any of them.
There wasn't even one iconic flying or landing scene in Superman Returns, which is unforgivable to be honest.
Especially after the hard work of Chris Reeve into making the flying look so perfect.
shame on those people who call themselves film makers and cannot even give us acceptable flying scenes.
