Selected scenes for my film's trailer

1) Flashback shots - possible two to give some background into the main character and her relationship. Also to give binary opposites to the person she becomes. Also to give a setting and equilibrium
2) shot of the alien spaceship arriving - lots of chaos and fear to tell the audience what the disruption is.
3) shot of Ben leaving to go the army, to give drama
4) shot of a very scary, ugly looking alien to present the villains. Possible explosions and gunfire in background to show the a-a genre
5) shot of Talia fighting a lot of aliens. This is to show the odds of human survival, and to again represent the a-a genre. The background could have a destroyed NYC scene to show the audience that the film is apocolypic
6) shots of Talia with her children to fortify the idea of her being a mother and present the USP
7)shots of other helpers and donors - John in a typical army uniform with an american flag and a cigar to create a stereotype.
8) some kind of surpring, scary alien shot to shock the audience and appeal to an older TA who may enjoy the idea of aliens and apolypse in a film.
