A quick and easy way to figure out the break even point for a movie is to double the production budget. It isn't always accurate, but it is usually close enough. The low-end estimate of Solo's budget was $250 million. So they would need, at least, $500m to reach the break even point. Could very well be much higher than that however as they effectively shot the entire movie twice and did several script rewrites.I’m too lazy to look, but I seem to remember hearing Solo had to make $400-$450 million to break even. The marketing costs were roughly $150 million IIRC and the movie budget was $250 million IIRC.
