I feel like I’m missing something, so perhaps there’s an aspect of corporate taxes here that I don’t understand. I would expect a write-off like this to reduce the assets of the firm on paper, perhaps having an impact on the market valuation, but don’t see how it would impact taxes.

Wouldn’t the actual expenses of production reduce tax liability immediately when they are incurred, regardless of whether or not the corporation later is able to make a profit off of the product? Or do they treat the production of a film as net-zero from a tax perspective because they had $X million in expenses and gained $X million in assets in the form of the finished film?

In the US, movie production costs aren't expensed in the period when incurred. They're capitalized, and then amortized over time.

So the last sentence of your comment is spot on.

Writing off an asset causes a reduction in net assets, which translates into a loss on the income statement.
