Virtual pub quizzes have almost become a quarantine cliché, but the latest celebrity edition is genuinely a bit special.

Husband and wife duo Imelda Staunton and Jim Carter are teaming up for a charity quiz with a joint Harry Potter and Downton Abbey theme.

They're calling it "Mr. Carson & Prof. Umbridge’s Ultimate Pub Quiz" after their respective characters from the two franchises: Carter's loyal butler Charles Carson and Staunton's menacing Hogwarts professor Dolores Umbridge.

They're hosting the quiz in aid of Marie Curie, a U.K. nonprofit which offers support to people living with terminal illnesses and their families. The quiz will take place on the Marie Curie Facebook page at 3:15 pm EST on Thursday, May 28, so there's plenty of time to brush up on your Harry Potter and Downton Abbey knowledge first.

Carter recently showed off his real-life butler-ing skills during Staunton's virtual appearance on The Graham Norton Show. The two actors have been married since 1983 and have a grown-up daughter together.

Marie Curie has been running a series of virtual pub quizzes during the coronavirus crisis. Last night Alison Steadman hosted a Gavin & Stacey-themed quiz which raised more than £40,000 ($49,000) for the organization.

A virtual Doctor Who pub quiz was also held recently to keep fans entertained as they practice social distancing.
