Credits and Billing analysis

I have noticed that one of the conventions I have found is that almost all of them include credits and billing. To make my poster as authentic as possible, I am going to include my own credits and billing.

I have analysed the credits and billing from two films of my chosen genre, one American and one British to see what appears in the billing and the order of elements in the billing. 

Billing from Sex Drive:

Billing from The Inbetweeners movie:

The Billing starts with production and distribution companies and finish with the names of the screen writers and the directors. After production companies comes the film title or the names of the main actors. The film title is then followed by the rest of the cast. In the middle I found various other crew such as casting, music composer, editors, cinematographers and various producers. 

Before I create my own billing I need to research potential crew that would best fit my genre and then create fictional actors to star in my film.
