Review any requirements given by your professor. Study these requirements carefully before you think about the plot. Length limits and genre requirements may influence the plot you select.
Select a topic that is of particular interest to you as well as one about which you have pre-existing knowledge to make the process less painstaking and more enjoyable.
Compose a script prior to making any casting decisions or getting others involved in the process.
Set a budget. If you are in college, you likely have little to spend. You may, however, have some money set aside for paint or costuming.
Enlist the help of friends, particularly if they are studying film as well, and ask them to serve as cast and crew. Seek someone to do the actual filming and perhaps even someone to assist in the editing process.
Create lists of what you expect each member of your film crew to accomplish to ensure that there is no confusion of roles in the film production process.
Gather equipment. You can likely borrow equipment from the film department if you are a film student. If so, take advantage of this opportunity. If you have difficulty with this borrowed equipment, it will likely be easy to find someone to assist you with it.
Film your scenes. Do several takes of each scene, even if it seemed perfect on the first shot, to ensure that you have all the footage to make a polished film.
Edit your footage. Using digital editing software, piece together your film, adjusting the sound or adding sound effects as necessary.
Add titles to polish the finished product. Include opening as well as closing titles, giving your creation the look of a professional film.
