Getting into character with a nearly unrecognizable look, Eva Mendes was hard at work on her latest film project on Tuesday (October 2).

The 38 year-old Tinseltown beauty ditched her everyday hotness as she rocked curly locks and an athletic ensemble while making her way around the Topsfield, MA set of “Clear History.”

As for the upcoming Larry David directed HBO production, the storyline focuses on a disgraced marketing executive who plots revenge against his former boss after walking away from an electric car company that ends up being worth millions.

Joining Miss Mendes in the star-studded cast are Kate Hudson, Michael Keaton and Jon Hamm, among many others.

While no exact release date has been revealed at the current time, you can expect to see “Clear History” hit the small screen in 2014.
