If you don’t make low-budget movies with your friends right now, you won’t make funded movies with professionals later.
Anyone can make a movie today with virtually no-budget and no crew, but few filmmakers want to take the plunge. Most are waiting for the “perfect time”, which never comes.
The best time to start making your movie (if you really do want to make one) is now.
There is aways an excuse to wait, but it never gets easier than making small indie films that you fully control. If you don’t like doing that, you probably won’t like the added challenge and complexity of larger projects.
