They usually use professionals to do the body to CGI switches instead of the actual actors, but some cases, such as Hulk in the Avengers worked because they decided to take the risk of using the actual actor. I mean, they can't use the actor in this case and someone has to do the movements.

The aliens won't be the actor 24/7. A majority of movements in the Spider-Man movies are completely CGI as well.
