Her first Marvel feature did quite well, but she had a good script, plus three excellent supporting actors.
In this film, both of her co-leads are ethnic quota females, and the trailer ads are lame.
According to Wiki, the film got a $55 million subsidy from the UK government.
Final cost (says Wiki) was $220 million, but we never know if that includes advertising, which can be very expensive.
Rule of thumb - $440 million box office just to break even, maybe more if high ad costs.
As thin as she is, I have to say I was impressed when I stumbled across a You Tube of her doing a one-arm pull up.
