From the actor's POV, if you're working for low money, or no money, on a project and your main compensation for the work is footage for your reel, you do want to get your hands on something as quickly as possible, especially if you think it's going to look good on your reel.
Everyone else gets paid during production or close to wrap - actors wait weeks, months - we sometimes never get our footage. Those who have been burned enough times learn to ask for footage as quickly as possible.
I think I remember Mike saying that post-production would not get finished until after his next tax return, which is months away.
Just pointing these things out, because everyone seems to be acting like the actress is a horrible person for wanting her payment in a timely fashion.

EDIT: Just checked my resume - I have five projects that I did not get footage from where footage was to be my sole compensation.
