Gabrielle writes in (via Twitter, which is why it’s so short):
The movie I worked on is still in pro&working under a mock title does the m.t. or the actual name go on the resume?
This is similar to a question Melissa asked a couple months ago, but it still bears addressing.
That’s all well and good if you don’t want nerds to crash the set of Transformers 4, but if you put “Robot Smashy” on your resume, people won’t recognize that you have experience on a big budget blockbuster.
Remember, the purpose of your resume is to show you have real experience. The mock title tells them nothing. Use the real title.
If it is, in fact, a working title, be prepared to update your resume as soon as the movie gets an official release date. Always use the title that people will recognize.
