I saw this recently! Exciting opportunity:

"Transformers: Age of Extinction" is now filming outside of Seattle, WA and extras are needed immediately for two all day shoots on October 8th and October 9th, 2013

Di Bonaventura Pictures and DreamWorks SKG in association with Hasbro are filming the Paramount Pictures science fiction action film "Transformers: Age of Extinction" (aka Transformers 4), and the casting director is seeking people available to work southwest of Seattle, WA as fully paid general extras and possible featured background actors. This is for people over 18 years of age, any ethnicity. No prior experience working as an extra or actor is required. The shooting dates are October 8th and October 9th, 2013.

I had no idea how this process works...check it out!
