Toy Story - Opening Sequence

The opening for 'Toy Story' sets the location as a child's bedroom in suburban America. It introduces a boy as one of the characters in the film but the camera mainly focusses on the toys. This gives the impression that these are the main characters. (and later in the sequence the toys start talking, reaffirming their role as the main characters) The budget of the film is presumably very high as it has a famous cast and a heavy amount of CGI and special effects. (The entire film is animated) With what is said by the main characters it suggests that the film is a comedy.
