What is a title sequence?

In summation, title sequences are used at the beginning of films to introduce producers, the cast, and the majority of the most significant contributors to the films production. Title sequence designers create title sequences that are effective, specifically with the typography used - the font used, generally fits in with the film's genre and plot. Title sequences are supposedly powerful initiations into the film that entices the audience to put them into the mood and setting of the film's environment.
