Where can i get a venom costume that looks just like venom in spider-man 3?

IN a xtremely expensive costume shop

Go to a Halloween costume store close near you.

on E-bay, after they finished filming, they post a lot of items on E-bay. It'll sell for at least $2,000!

Just ask........ :)

you might as well jump into a vat of steamy hot gloopy tar and there you go youll look like venom amazingly you could beat anyone in a fight coz you will hurt them hahaha
