Okay, so you know how sometimes when grown-ups or big companies get into a big argument or problem, they might go to a special place called a courthouse to talk about it and try to figure out who's right or wrong? Well, sometimes people bring cameras and record everything that's happening in the courthouse. This is called a trial film.
A trial film is like a movie of what happens in the courthouse during a trial. The camera follows the people involved in the case, like the lawyers, the judge, and the people who are arguing over something. Sometimes there are witnesses, which are people who saw what happened and can give their side of the story. The camera might show them too.
The trial film is important because it helps people who aren't in the courthouse to understand what's going on. It's like a big news report that shows all the important parts of the trial, so people can see who is right and who is wrong. Sometimes, the trial film is used later on if the case goes to a higher court or if there's an appeal.
Overall, a trial film is like a special type of movie used to show what happens in a courthouse during a trial. It helps people understand what's going on and can be used for important legal purposes.
