X-Men
Wolverine is well-known as the mutant with the ability to regenerate himself no matter what kind of damage he undergoes. Regardless of whether it is a stab wound or a gunshot, he never fails to return angrier than ever. Little kids probably stared in wonder whenever it happened. This scene comes from X-Men: Days of Future Past and shows cast members setting the actor up for success. As the snakes go through him, it seems like they were only attached on the outside. Pretty cool, huh?
Godzilla
While there is a possibility that there are actual giant lizards lying in wait out there, we simply have not seen them yet. More to the point, it would probably be the end of the world. While a nuke could maybe put a stop to such a creature, we all know that civilians might get caught in the crossfire. That’s why they had to put this green screen in front of the actors! You must have noticed the nice effects in Godzilla!
