Fan Casting Sharon Carter in George Nolfi's Captain America

Many of the details of Sharon Carter's early life are as yet unrevealed. She is the grand-niece of Peggy Carter, the late wife of Captain America, and grew up being told tales of her famous great-uncle (see Captain America). As an adult, Sharon decided to enter law enforcement. Due to her familial relations, while attending the FBI Academy she was recruited into SHIELD, becoming one of their top special agents. She would often take the name "Kate" when performing undercover investigations. When Captain America returned to active duty, Sharon was assigned to work with him as his official SHEILD liaison. Sharon was at first apprehensive about working with her "Uncle Steve" (as she called him), but was surprised to discover how young he remained – the two had not actually met since she was a young child. This soon turned towards a bit of resentment as he would actively try to shield her from harm, until she released "the fabled Carter temper" at him, giving him a piece of her mind about his overly-protective treatment. Since then, the two have tried to work as equals, with Sharon assisting in helping train Cap's new partner, Rikki Buchanan, the new Bucky.
