That debut was to the tune of $121 million which means the film starring Chris Hemsworth is the 7th biggest opening for an MCU film.
To round out the numbers its also the 17th number one film from the Disney series and the 8th which has delivered a $100 million plus opening, it beats Spiderman Homecoming from earlier this year.
With Thor out of the way last weeks halloween hit Jigsaw, as expected, falls hard this week and ends up at number 3 with $6.7 million, its total US gross now sits just below $30 million.
Also new on the US box office this week is A Bad Moms Christmas, maybe a little early for people to be thinking of the Christmas season but the film makes a very impressive debut at 2 with $17 million.
Longest running film on the US top 10 is Blade Runner 2049 which clocks up 5 weeks and with its impressive $122 million debut Thor: Ragnarok is the highest grossing movie on the chart, it has been a very slow second half to the year, until now.
