Bookings from as far away as the USA, Canada and Greece have been made for the plays, which will be the biggest outdoor theatrical performance in Britain this year when they take place in August.
The naming of the two professional actors, Ferdinand Kingsley and former Coronation Street villain Graeme Hawley, has caused a recent spike in tickets being bought, with more than a thousand sold in the last week.
Rachel Naylor, Box Office Manager for York Theatre Royal, said: “The response in recent weeks has been outstanding with the matinee performances in particular selling well. I think the naming of the two professional actors has spurred people into buying tickets, but also the recent hot weather may have made people start thinking about the summer and how fantastic it will be to see theatre in the York Museum Gardens.
“I would recommend that if you have friends and family visiting on a specific date to book as early as possible to avoid being disappointed.”
With 10,000 tickets sold, almost a third of the total tickets have now been snapped up, with weekend evenings filling up quickly and some of the matinees close to selling out. International sales are also increasing, with groups coming from across Europe and North America to witness the most complete cycle of medieval mystery plays, including a recent large group booking from the Netherlands.
Tickets can be bought in person from the York Theatre Royal Box Office, by phoning on 01904 623568 or by going to the theatre website.
