The first time she read the script, Marimar Vega knew she had to do it, no matter that it was her first nudity and about an incestuous relationship. Her father, actor Gonzalo Vega, told her that in acting you had to take risks and her sister Zuria, also an actress, told her that the story was worth it. These were the only opinions Marimar, heard before going to talk with director Michel Franco. "There were some nerves about the nudity that had to be done, but when I talked to him and he explained how he was going to work with me, how he was going to take it, they went away," she recalls.
