There, you can see Tom shooting the scene, he`s upper a plataform seeing at the bottom, of course Tom is fixed by security wires. There`s a green screen, so all the details about the scenary will be added by special effects.
There are other photos where you can see Tom without the coat, just in t-shirt wearing a harness (Oh! Thank Goodness...They take care of him)...he looks awesome!!!
