The long-running Korean non-verbal theater play "Nanta" topped 10 million in the accumulated number of viewers at home and abroad last year, becoming the most-viewed domestic play of all time, the show's production company said Friday. The performance has sold 10,085,010 million tickets at four exclusive theaters -- two in Seoul, one on the southern resort island of Jeju and one in Bangkok -- until Dec. 31, the PMC Production said in a release.
