Sean Penn and girlfriend Charlize Theron are collaborating for a new movie as the dating A-listers take on a love story with Oscar winner Javier Bardem deep in Africa.

This time around Charlize Theron will take orders from rumored fiancé Sean Penn who will helm "The Last Face." According to Deadline, production will start as soon as River Road and producers Bill Pohlad, Bill Gerber and Matt Palmieri will give their go signal.

Also included in the powerful cast is Academy award nominee Adèle Exarchopoulos ("Blue is the Warmest Color"), who is reportedly playing a journalist.

In the film, Charlize Theron will play a doctor who volunteered for a humanitarian relief work in Africa while facing the challenges posed by political strife in the country. There, she meets another doctor played by Javier Bardem and together they find love amid the chaos.

Being South African, this would be right Charlize Theron's alley.

The website added that it will be the fourth collaboration between Sean Penn and Bill Pohlad including critically acclaimed "Into the Wild," "Fair Game" and "Tree of Life," which was directed by Terence Malick and narrated by Sean Penn.

Both Javier Bardem and Sean Penn just finished production for "The Gunman," which is a story about a spy who must save himself from the organization that he works for.

Last month, South African Sun-Times ran an article about Sean Penn and Charlize Theron looking for engagement rings in some local jewelry stores. The story was later proven to be false.

In Touch also suggested that Sean Penn and Charlize Theron are already engaged despite only being together for a few months.

"This one's a little bit of a head scratcher, because who would have thought that Sean and Charlize would even get together, much less get so serious so quickly?" celebritydirtylaundry.com said.

Charlize Theron in an earlier interview said that she doesn't believe in the concept of marriage.
