Left 4 Dead 2

So while playing Left 4 Dead 2 this morning, I started to consider how cool it would be if someone created a movie; plus it would be extremely popular. You would not just have the video game audience, you would also have people who enjoy anything zombie, as well as people who like horror type movies. Plus being one of the most popular games on the market currently, you would hardly need to publicize it, once people hear Left 4 Dead movie, I gurantee you'd have thousands of people interested.
So I got to thinking who would play each of the characters:
well Rochelle was easy for me, I think Jada Pinkett Smith would make an excellent Rochelle, not only does she kinda look like her but she can also be a kind of bad ass at times with a sassy attitude that would be perfect for the character.
Coach was kind of easy for me as well, I think Ving Rhames would play a great Coach, although he is very muscular and not fat like in the video games, he still has the look going for him and having seen him in other zombie movies, I think he would make the perfect character for the movie.
So then I got to thinking who would play Ellis and Nick. Well semi-recently, a few months ago, I saw the movie Legion, and in that movie was Lucas Black and in certain scenes he just really reminded me of Ellis. So I think he would make the perfect Ellis.
Now Nick was a hard one, honestly he kind of looks like Russel Crow so if I were to go by looks, I would choose him to play the character so that we could keep the actors kind of looking like the video game characters. But personality wise, I don't really know so I would just kind of go with him.
So that is who I would cast if I were to make a Left 4 Dead 2 movie, I'm still thinking about the cast of the first movie though and will post later with who I would think would make the perfect characters for that. But I wouldn't just go straight into the zombie killing of this movie, I would start out by showing a little bit of each of their back stories which would help explain how they got to surviving the zombies.
