If going by the listings on LA Craigslist, it appears that Transformers 3 production has begun to look for extras for filming. No date is specified on when filming may begin. Extras are those people you see walking and talking in the background of scenes that are seen but rarely ever heard.
Here is an example ad:
It's Amazing,Spielberg is back to work again.I do not know anything about how extra casting works so no idea if using Craigslist is the norm or not. A quick Google on the provided phone number doesn't provide any clues on legitimacy one way or the other. If you are in the LA area and curious I just recommend caution. Remember the goal is to hire and pay you for your time so if they ask for money it is probably a scam.
