Anna Paquin: Mackenzie Siler
As Zack’s younger sister, Mackenzie, Anna seems wise beyond her teenaged years and takes the reins when it comes to Laney’s big makeover. She’s All That was arguably Anna’s first stab at a teen film, having appeared in a number of period films, including The Piano, which earned her a Best Supporting Actress Oscar at age 11.
Post-She’s All That, Anna took on big blockbusters (the X-Men franchise), quirky indie films (Buffalo Soldiers, The Squid and the Whale), and dark dramas (The 25th Hour). Fans now know her best as Sookie Stackhouse on the hit HBO show True Blood. Married to her co-star Stephen Moyer since 2010, Anna gave birth to twins in September 2012.
