Reasons:

lovebaltor: "This was a little difficult for me. I definitely know more actress' than actors, so I had to think a bit for this one. I decided that I was going to go with Aidan Turner. I first saw him was in "The Hobbit: An Unexpected Adventure" and I thought he was rather adorable. He was goofy, but he was also serious and a really good fighter. (With both bow and sword) He's played heroics before, so I'm sure he can make a good Brandon."

winxoxoxclub: "1:he is cute
2: his hair
3: he is funny
4:hes a lovebird like Brandon
(Well i personally think he is cute-do u?)
5:hes loveable
6:this could go on forever."

zanhar1: "I'm gonna go old school and pick Drake Bell as he in the show Drake and Josh (obviously) he played himself as this 'good-looking', macho, ladies man type guy. He was the 'smooth' and not so bright one, always gets 'the hot babes'! And I sort of see these qualities in Brandon. He is also similar appearance wise, pre-facial hair that is."

zikkiforever: "Zac is similar to Brandon appearance wise I think from the hair to the clothes and such. Zac is best known as Troy in high school musical where he played an athlete ,which I think Brandon is like. I find both personality's very bubbly. Then in season 4 Mitzi likes Brandon ,but he likes Stella ,so a love triangle and in High School Muiscal that was happening. Sharpay liked Troy ,but Troy liked Gabriella. I think they face the same issues. Also, I think both can be a bit of a player love wise and has girl falling at their feet. Brandon-Mitzi,Stella and Amentia. Troy-Sharpay and Gabriella."

No I go with Drake Bell.

I don't like any of the others one bit

I don't like Zac.

I feel like Zac is a good match.

Definitely!
Also Louis.

I love Drake and saw him and was like no doubt he will get my vote,I loved his music,in Drake and Josh,Zoey 101(guest appearance) and Grow Up Timmy Turner(nick special). I am looking now and see he might be a little too old for the part you know? I still love him ,but cosnsidering age I am unsure.

Louis was my pick ,because I think he could do it with some acting lessons.

Aiden seems again a tiny bit too old and I can't see a match appearance wise.

So overall Louis or Drake.

This guy looks perfect for playing Brandon.

This guy

Louis too.
