Hello
It's very easy to become an actor for GR8 pictures.
Somebody will just have to meet you on San Andreas multiplayer, and see if you are mature enough.
You don't have to be very smart, sometimes standing somewhere is already enough to 'act'.
Things you need to have:
-GTA San Andreas multiplayer.
-Brains
-You have to speak English (a little bit)
Believe me, if you have GTA SA, then it's very easy.
Greetz, B
