If a live-action series of Kanto was created...

I know this is going out on a limb, but it's more for fun than anything. What if a Pokemon live-action movie or series was made today? How would you cast it? Whether it's based off the anime or the RPG with a different twist I think it would be an incredibly interesting showing.

So my question for everyone is-
Who would portray the protagonist?
Who would portray the 8 gym leaders(and E4 if you'd like?)
Who would portray Jesse and James/team rocket portions?
and most importantly, who would play Oak???

There really would be a lot of options for this hypothetical really I look forward to your responses.

My choices would be;
Protagonist/Ash - Andrew Garfield
Brock - Terrence Howard
Misty - Emma Stone
Lt. Surge - Brad Pitt
Erika - Natalie Portman
Sabrina - Helena Bonham Carter
Koga - Alan Rickman(who wouldn't want to see that?)
Blaine - Paul Giamatti
Giovanni - Christopher Walken

As for the E4 I don't think much else would matter as long as Betty White played Agatha.

with Dustin Hoffman as Professor Oak, but I know there's a better option out there.

Once again this is just for fun, anyone with ideas please toss em out there!

I remember that there's a Pokemon live action trailer (mock one, as far as I know), so you can take a look at that and see how they do. Here's the video:

That's it for now.

Andrew Garfield?

Yes, because a 28-year-old British-American guy can portray a 10-year-old from a vaguely Asian region.
