Order of titles in our opening sequence

When I was editing the titles into our teen film I had to follow the order that the titles appear in movies.
The opening sequence begins with the distribution ident and is followed by the production ident. These idents are both made in motion and the names of the two companies have been made up as a group. The distribution and production companies come up as title next when the teen film begins. Next is the list of names of the actors that are in the film. This list of names includes the most payed actors and the stars in the film. Next are the names of  the casting, the costume designer, music director, editor, production designer, executive producer, producer, writer and last is the director.
When I was making the titles and coming up with the names of crew members I had to make sure that  a name of a person wasn't stated twice, as in films you wouldn't see someones name come up for two different things, one person has their own individual job in the making of the film.
This list of titles that is seen at the beginning of our teen film is important as like in normal films all of the most important actors and crew members.
