Krypton's Wallis Day Went as Joaquin Phoenix's Joker For Halloween

It would be hard to find very many people in the geek space who have not seen Joker at this point. With over $800 million at the global box office, awards buzz, and a seemingly-unending supply of controversy and consternation, the film is not only the highest-grossing R-rated movie of all time, but is likely to be a defining element of this year's film discourse. It's no surprise, then, that a number of celebrities are likely to be dressing as Joaquin Phoenix's Arthur Fleck as Halloween nears. It's pretty interesting, though, to see Superman's grandmother get in on the face-painting action.

That would be Wallis Day, the British actress who played Nyssa Vex, the mother of Jor-El in the late, lamented SYFY Superman prequel series Krypton.

Krypton took place 200 years ago, and centered on the character of Seg-El (Cameron Cuffe), Superman's grandfather. In the first season, Brainiac threatened the city of Kandor on Krypton, but was turned back when Seg teamed up with General Dru-Zod (Colin Salmon), who turned out to be his son from the future. Seg's other son, Jor-El (who would go on to be Superman's father), was born during season two, meaning that at one point Seg would have had a child with both of his two love interests on the series, Lyta-Zod (Georgina Campbell) and Nyssa Vex (Wallis Day).

Joker has made $250 million at the domestic box office. It's made over $700 million worldwide and has a shot at becoming the highest-grossing R-rated film of all time. It is already Warner Bros.'s biggest release of 2019.

Joker is a grounded, R-rated origin story for Batman's arch-nemesis, the Joker. Phoenix plays Arthur Fleck, who descends into madness and emerges as the clown-faced killer known as the Joker. The film also stars Robert De Niro, Zazie Beetz, Frances Conroy, Brett Cullen, Glenn Fleshler, Bill Camp, Shea Whigham, and Marc Maron.

Joker is in theaters now. Upcoming DC Films movies include Birds of Prey (And the Fantabulous Emancipation of One Harley Quinn) on February 7, 2020, Wonder Woman 1984 on June 5, 2020, The Batman on June 25, 2021, The Suicide Squad on August 6, 2021, and Aquaman 2 on December 16, 2022.
