[T]he one indispensable ingredient of science fiction [is] a belief in a world being changed by man's intellect, a conviction that what was being written could really happen.

In hard-core science fiction in which characters are responding to a change in environment, caused by nature or the universe or technology, what readers want to see is how people cope, and so the character are present to cope, or fail to cope.

In science fiction a fantastic event or development is considered rationally.

I love Groot so much I get teary eyed when I think of him sometimes. Essentially, all the Guardians start out the movie as bastards - except Groot. He’s an innocent. He’s a hundred percent deadly and a hundred percent sweet. He’s caught up in Rocket’s life, really.

It's definitely not the character who it is in the comics, I'll say that much.

I like to plan everything out and know exactly what we're doing. It's always important to me to work with a cast and a crew that not only I respect their talent but I really like them as people.

I always like to think that I make movies that are like Nirvana songs. They have a slow verse and then they pop into high gear and then they go back into slow and then they pop into high gear again.
