Director James Gunn's Guardians of the Galaxy Vol.2 opened to a stellar $6.6 million in its first three foreign markets on Tuesday as it began its international assault in 58 territories this weekend, a week ahead of its May 5 launch in North America.

So far, the Disney and Marvel sequel is pacing well ahead of the first film. Guardians Vol. 2 debuted to $4.5 million in Australia, including previews. That's three times more than Guardians of the Galaxy in August 2014. It is also the second-highest opening day for any Marvel release behind The Avengers.
