I'm not entirely sure if the 'Alice film' is based on a true story without more context. It could be a small - budget indie film that tells a real - life story of an Alice, or it could be a completely made - up story with the name 'Alice' just used as a character name. There are so many films out there, and more details about this specific 'Alice film' would be needed to give a definite answer.
Yes, it could be. If it's a true story, it might be a documentary. But it could also be a fictionalized account based on a true story in the form of a regular film.
It's more likely that Alice is a work of imagination. Usually, authors create such characters and stories from their creativity rather than real-life events.
I don't think so. Usually, such works are imaginative and not tied to actual happenings. Maybe there are elements inspired by real life, but not a full-on true story.
Alice is generally not based on a true story. It's more likely a figment of the author's imagination or a fictional construct designed to entertain and engage the audience.
