Karen had gotten wind of the Guardians of the Galaxy 2 film. Reading about Nebula coming into contact with an Asgardian device, granting her godlike strength. Taking her acting serious, she quickly locked herself in the gym, training to make the part work. She hated the thought of having to need a stand in or CGI enhances body. When the casting began she reported for her part is Nebula. Having misunderstood the script, Nebula was to gain godlike strength, without the physicall change. However the studio quickly decided on a change in the script. Renaming the movie "The rise of Nebula", with as payoff: Guardians of the galaxy 2.
I had a chat with a friend about Karen Gillan yesterday, which made me feel like doing one!
