WATCH: Dame Helen Mirren and Friends Host National Theatre Online Quiz

The U.K.'s National Theatre has a "home edition," currently streaming the 2011 Frankenstein stage production, starring Benedict Cumberbatch and Jonny Lee Miller. Every Thursday, a new program will be released via YouTube, which you will have up to seven days to watch for free.

In addition to airing fan favorite productions, they've also come up with a new and fun way to keep in touch with theatergoers. Artistic director Rufus Norris has recruited some major acting heavyweights to host an online quiz, with the first installment including Dame Helen Mirren, Sir Ian McKellen, Lenny Henry and Lesley Manville.

Dame Helen kicks off the quiz, saying, "I have five tricky questions for you." She reads off the first question: "By what name did the Romans call Ireland?" The second question is a little easier: "Who was the first president of the 50 states of the United States of America?"

Actually, the second question is tricky. She's not asking who the first president was, but more specifically, the first president of all 50 states. We caught it! Do you want to test your knowledge?

The rounds will be made up of questions pulling from topics like history, sports, nature, and... the National Theatre itself. In the above, Henry handles sports, Manville is responsible for the Theatre and McKellen swoops in for the "bonus round."

Each quiz will go up on the last Monday of the month at 7pm BST (2pm EST). You can tally your results at home and just play for fun. Or, post your results on the National Theatre's Facebook or Twitter pages, which is also just for fun.

The hardest question of all is... who has the best stay-at-home look!?
