Wallis Day

British actress Wallis Day's turn in attention-grabbing roles in series like "Hollyoaks" (Channel 4, 1995- ) and "The Royals" (E!, 2015- ) led to her American television debut on the highly anticipated "Krypton" (2018- ) for Syfy.

Born September 20, 1994 in London, England and raised in the town of Illford, she fell in love with performance after being taken to see ballet at the age of five by her father. Day soon began taking stage lessons in Oxford and at the Sylvia Young Theatre School in London before moving on to formal training at the Tring Park School for the Performing Arts.

While honing her craft, Day also worked as a model, but soon focused her attention on acting after landing her breakout role in 2012 as Holly Cunningham on the popular primetime UK drama "Hollyoaks" (Channel 4, 1995- ). Day replaced actress Lydia Walters - the third of five actresses to play Holly over a two-decade period - to play the teenager, who ran afoul of older men and other soap opera perils during her year-long stint on the program and its spin-off, the more adult-themed "Hollyoaks Later" (Channel 4, 2008-2014).

She departed both series in 2013 for a string of guest roles on various series, including recurring role on "Jekyll & Hyde" (ITV, 2015-16) as the granddaughter of the infamous Henry Jekyll, who shared his propensity for transformation under duress, and on "The Royals" as Angie Davis, sister of meddling bartender Kathryn Davis (Christina Wolfe) who briefly impersonates palace maid Violet (Keely Hazell).

Day made her American television debut on "Will" (TNT, 2017) before landing her breakout Stateside role as Nyssa-Vex, a lawyer on Superman's home planet, on "Krypton," a prequel series to the iconic DC Comics' character's origin story.
