If any anime adaption could translate to the big screen well and seamlessly to the western well then I couldn't think of a better choice than Death Note. It's a story that can pretty much take place anywhere in the world and still stay faithful to the source material. Japan has made a decent live action adaption and also took some creative liberties that even surpassed the original source material.
I don't care what you people say but the ending for the live action films are basically how it SHOULD HAVE ENDED. Better than both the anime and manga no question. It should have always ended between Light and L.
With this American remake confirmed I thought I'd play around with some fan casting options. So here we go.
Light Yagami (my western name suggestion for the hell of it could be something like Luke)
Option 1: Zac Efron

CALM THE EFF DOWN AND HEAR ME OUT FOR A MINUTE!
Now, I know this rumor is taboo but I think this guy is unfairly criticized when it came to this because all that ever came up was High School Musical. That's not the only thing he has done. He has expanded his acting range and shown that he's capable of doing dramatic roles. Zac is the dude who needs to shed that Disney skin completely in order to be taken a little more seriously because there's potential there. Maybe playing a darker character such as Light will help out with that and not to mention he also is an AVID FAN OF THE SOURCE MATERIAL. He knows who Light is. He loves Death Note and expresses personal interest in the project.
All I'm saying is I'm willing to give this a chance.
Option 2:Alex Russell

He's a newcomer best known for his role in Chronicle playing Matt. Chronicle was a flick that surprised the hell outta me and was one of my favorite films of that year. Featuring some new great and young talent, why not really?
Option 3: Tom Welling from Smallville fame?
L: Cilian Murphy

Personally I think for L it's a dead ringer. L is not supposed to be Japanese. He's a rather Lanky dude and also not really supposed to be attractive. Get a little bit of make up on him and make him look a tad sickly and I'm telling you this is like perfect casting. He's a pretty good actor and I can see this happening.
Misa Amane: Olivia Thirlby

She's a young and also rather talented actor. She's played in oscar winning films like Juno and was the blond girl in the awesome and overlooked Dredd. (Seriously, Dredd was awesome and you people should like totally watch it so we can get a goddamn sequel) Ditzy energetic blond pop star, check.
Soichiro Yagami:Gary Oldman

I can't quite put my finger on it but like, I think he totally could play Light's dad. I don't know why. I just have a feeling.

Ryuk: Voice: Same guy from the anime
Motion capture actor: Andy Serkis (duh).
Rem: Voice same person from anime but if on the off chance it would have to be someone different then Sigourney Weaver.
Add whatever suggestion and feedback you want. Keep it civil and cool guys.
