There are two main production companies which are shown at the beginning. This suggests that they are important production company in the making towards the movie.
Next is "the DAVID FINCHER film" who is then mentioned again at the end as he is the Director! As this is named it suggests that he is well known otherwise they wouldn't write it. After this is the main actor DAVID CRAIG and then ROONEY MARA.

As these actors are shown therefore they are all important in the film otherwise they would not be mentioned. After this the casting director is named, then the costume designer, next is the co-producers of which there are two, then sound design and music. The editors are then mentioned and then production design and director of photography.
