Solange Knowles as Angelica Schuyler
To play the role of Eliza Schuyler's sister, Angelica, why not get Beyoncé's actual sister, Solange? Angelica introduces her sister to Alexander but continues to covet him herself. Better yet, Angelica's songs would fit Solange's vocal style. Alicia Keys would also be an excellent choice for this part.
