Beyond that, the video game adaptation filmed in Morocco, which means that could be the production referred to in her comments.
Gemma Arterton did not mention this specific film by name during her appearance on The Guilty Feminist podcast, but some have already begun to theorize about the possible film in question.
The former Bond girl has previously spoken out about the uncomfortable process of losing weight for her role as Tamina in 2010’s Prince of Persia: The Sands of Time, so that certainly seems like a viable option.
Prince of Persia star Jake Gyllenhaal notably increased his own muscle tone for the movie as well, so it would obviously prove interesting to be able to go back and see how the production monitored his diet and workout schedule at the time, too.
