Let's do some rough maths. Mulan was around $200m to make, they spent probably $100m on advertising pre-covid, maybe $150m, so lets say $350m total for argument sake. They're not splitting the revenue, so at a minimum they need about 12 million people paying $30 to roughly breakeven. If they have 60 million subscribers they need roughly one-fifth of those subscribers to make their money back on the film. It's not impossible, but I'm also not convinced it's likely, especially when they already announced when it's coming free to the service.
