Re: A Spider-Woman film?
In the comic book world, where you've got literally thousands of heroes and villains to work with, that origin story works for Jess. But in the movies, where the super population is by necessity severely limited by the number of movies/TV shows you can put out each year, having the (wo)man-out-of-time motif again would severely detract from Cap....and now Bucky, too. There's only so many times you can go back to that same well before it runs dry.
The slow aging thing would most likely be dropped completely from an MCU Spider-Woman.
