Thor: The Dark World opened to an estimated $7.1 million for Thursday preview showings in advance of today’s North American opening in 3,841 theaters — including more than 3,100 3D locations. Overseas, the Marvel/Disney sequel starring Chris Hemsworth and Natalie Portman added another $10.9M in box office yesterday from key markets including the UK, Russia, and France, boosting its international cume to $152.8M. That’s before today’s expected big opening in China and other smaller markets, which will put the pic out in 92% of the world. Last night’s domestic preview grosses topped previous Thursday grosses for Thor ($3.2M) and Captain America: The First Avenger ($4M), both in 2011. The first Thor opened domestically in May of that year with $65.7M in its first weekend, on its way to $181M here and $268M overseas.
