Title of film

I need to decide on a title for my film. I want my title to have meaning towards the plot of the film and to also be short and snappy as these sort of titles stick in peoples minds.

These are some of the titles I have brainstormed:

• SERIAL
• Who's next?
• Meurtrier en série
  
• Are you next?
• Slasher
• Murder
• Targeted
• Final Target!
• Last one

I have decided I like the title ‘Last One’ as I find it catchy and it has meaning.
The meaning behind it is basically the rest of the story.
The basic plot of the story is…

A man (a bit like a ‘Hitman’) and he has been hired to murder 15 certain people. The main part of the story will be about the ‘Last Person’ being a hard target to murder.

My opening sequence is showing the kind of character this man is, and to give the audience an idea that he is a ‘Hitman.’ It also shows a victim being murdered.
