I know what you mean, yet I have a very strong feeling that there is a ton of stuff that we know nothing about yet.
In addition to a certain someone who has not been featured in any footage or stills, I’m willing to bet several exciting sequences or locations are still being kept under wraps.
Is it a spoiler to reveal that yes, I am in the movie like you were hoping?
I ride up on horseback at the end of the movie and interrupt the wedding for the robot ball and the vacuum cleaner, so I can be the one to give away the robot ball.
