TITLES
Distribution and Production credits
Inter titles
Their function is to inform the audience on things like institutional details, character names, actors names, etc.
What We Do In The Shadows and Surf's Up,use inter titles with the character names on them. 
Almost all mockumentaries have inter titles with character names and roles on them.
What We Do In The Shadows - there are no company credits in the opening sequence of this film, but we had to use some in order to follow the conventions of film opening sequences, so we looked at other films for guidance.
A Sight For Sore Eyes - it is not conventional to have institutional credits in mockumentary film openings other than the first inter title, so we used the same technique as in Surf's Up.
Surf's up - the institutional credits are shown on a clapperboard in the first shot.
