Creating Characters for Novels/Movies


Have you ever wanted to write a novel or movie script but weren’t sure where to start? Characters are a great place, since they drive the story forward and make the reader care. This series will cover how to create protagonists and antagonists, set up character arcs, and center your characters around the core theme of the story (and how to find the theme). We’ll also touch on story structure to give you the context in which your characters will exist in the story, and I’ll give you some tips for how to actually finish your first draft. If you have attended my series on short story writing, that’s awesome! However, no prior experience in writing is necessary to join! I’ll do my best to make the series as beginner-friendly as possible. :)

College Advice

Supplementals (Part 1 of 2): How to write the "why us" and "community" essays? (We'll add more common topics if there's time.) There will be 3 more sessions about essays (we couldn’t make them all a series because we wouldn’t have been able to co-host then), so just take a look at either of our profiles to sign up for them!

She was really kind and showed us slides about achiving goals for New Years! she explained well and gave us enough time to think about the goals we wanted to do and how we could achieve it. She was very helpful throughout the meeting and helped me understand more about the topic we were doing.
