It's possible that:
* You've misremembered the title: Double check the title and try searching for a slightly different variation.
* The film/media is obscure: If it's a very niche or independent production, information may be hard to find online.
* You're thinking of a different production: Maybe there's a similar title or concept that you're associating with "Generation Lost - 2001".
To help find the information you need, please provide more context. For example:
* What genre is the film or media?
* Who are the actors or creators involved?
* Where did you encounter the title?
