How to Train Your Dragon 3 opened at No. 1 in 20 of the 23 international markets it debuted in during this session. The film made $8.7 million in Mexico, marking the biggest weekend launch ever for a DreamWorks Animation movie in that country. Deadline said the U.K. debut of $6.8 million was better than the launch of the previous two films, and they added that Italy was also tracking ahead of the first two films in the HTTYD franchise. So far, so good.
