Thor: Ragnarok took in $14.5 million in North American theaters during preview screenings on November 2, according to The Hollywood Reporter, keeping the film on track for a predicted $100-$120 million plus debut weekend.
That would make Ragnarok the top opening for a Thor film. 2011's Thor took in $65.7 million during its first domestic weekend, while 2013's Thor: The Dark World had an $85.7 million domestic opening.
It also makes it the fourth-best Thursday night 'preview' of 2017 after Guardians of the Galaxy Vol. 2 ($17m), Beauty and the Beast ($16.3m) and Spider-Man: Homecoming ($15.4m).
Last November's Doctor Strange made $9.4m on Thursday on its way to $85m its opening weekend.
It is also one of Marvel's best reviewed films, currently sitting at a 94% "Fresh" rating on Rotten Tomatoes.
Thor: Ragnarok has already grossed $180.8m on the worldwide market so far, including a $16.3m opening Friday in China. It is now in theaters in North America, China, and other territories.
