What is the email address for Troublemaker Studios?

I am sure you found Troublemaker Studios here www.loshooligans.com.
It's just as well Rodriguez directs movies because he'd starve as a
web designer.

Film production companies sometimes establish a company name for just
one film. If neither Rodriguez or Troublemaker are listed in the Texas
phone book, your best bet is to register for a free account here
https://secure.imdb.com/signup/v4/?d=IMDbTab. It's good for 14 days.

By searching for Rodriguez or the company, you will get his agent's
name and contact details and possibly the company as well.

You will definitely find this info as www.pkbaseline.com, but it will cost you.
