Any problems with Filming.

One of the main problems with filming at first was that i kept changing my ideas for the film. I must have changed about 7 times. What annoyed me about that was the it was only until the last month could i finally start productive work on the film. Also when it did come to filming, it was very hard to film due to dates. for example, when i was free to film, my actor wasn't. or the location was busy, or the mise en scene was not right e.g. bad weather. I literally had to wait for the perfect time to film.
