Yes, of course I would watch this movie

Yay, Anne and Mary. There may not be a movie about them, but at least they're pretty good units in FGO.

Not so much lesbian pirates as bisexual pirates (which, honestly, would properly describe most pirates/sailors of the era). Anne was actually the lover of Captain Calico Jack, and both Mary and Anne avoided being hanged for their crimes with the rest of his crew upon capture because they were pregnant.

The makers of Gentleman Jack should pick this up for a pitch!
