#8: Helen McCrory as Bellatrix Lestrange
Originally, Helen McCrory was cast in the role of Bellatrix Lestrange, but after becoming pregnant, she was forced to drop out; Helena Bonham Carter took over playing this role, giving fans a villain they would never forget. McCrory would later be cast in the series as Narcissa Malfoy, and thus re-entered a different yet rather pivotal role.
