Analysis of compaerable openings

Wall-E does have many of the different conventions of an opening sequence, at the end of the sequence the title of the film, Wall-E, is overlaid to take up most of the screen it also introduces you to the main character who is a robot called Wall-E this also give a Strong impression that most if not all of the other characters will also be robots.
It also set the tone of the movie by having the sober tones of an abandoned earth yet also with the light hearted comedic tones of Wall-E having befriended a small insect, probably a cockroach. By using these tones it help to set the genre of a comedy for younger audiences and it sets up questions for the rest of the film like where has everybody gone?
besides this it also missed out some key components of an opening sequence as it does not have any of the cast and crews names also it does not give much of a clue to the time period but it does suggest that it is in the future and the it also does not have a signature theme tune like most movies but it does have a sound bit of Wall-E saying his name.
