Order of the titles in the opening scene. This helps us to create the right order for our own thriller.
So, I analyzed the opening scene of signs.
1) 0:03sec - Label that presents the film
2) 0: 10sec - Business that Produced the film
3) 0:17sec - The first actor is shown, who is the main actor
4) 0:23sec - The second actor is shown
5) 0:29sec - The name of the film
6) until her - 0:44sec - other actors
7) 0:45sec - casting by..
8) 0:51sec - Music by
9) 0:59sec - Visual effects Supervision
10) 1:04sec - Costume Designer
11) 1:10sec - Edited by
12) 1:15sec - Production Designer
13) 1:20sec - Director of Photography
14) 1:25sec - Executive Producer
15) 1:30sec - Produced by person X and Y
16) 1:35sec - written, produced and directed by..
I recognized that between most of the titles have a gap of 5sec between each others.
This relies to my first point.
