6. Pick your favourite film and analyse the type of title sequence it uses

The type of title opening here is a "Stylist" opening, with the time vortex in the intro setting the scene and telling us this is a sci fi film. You don't often see a flying blue box in space travelling through colourful lights and stars, so it is trying to give the audience a feel of what is to come.

As for the order of the credits, you firstly see the name of the film, shortly followed by a list of actors and important people. Usually the first people you see are the main characters.
