Solo also had an opening crawl.
I mean, It could have been a crawl, but it didn’t actually… crawl.
I feel like just cold-opening is the best call, but if you feel like you need it something up front to make it “feel theatrical” I’d agree with the post above that suggests you do it in the A Long Time Ago font like Solo did, and fade the text in and out between paragraphs
It didn’t crawl, but it served the function that the crawl serves… it was just executed poorly in Solo. With the convoluted setup, and how much has been cut in that first act, I think a traditional crawl is helpful. That allows a context to be formed about who The Mandalorian is and why he’s travelling to retrieve The Child. Also, with the goal of making it feel like a traditional Star Wars film, instead of the anthology content it already is, using the format of a traditional saga film makes sense.
