* You're thinking of a different year: There might be a film with that title released in a different year.
* The title is slightly different: Perhaps you remember the title incorrectly. A quick search for "Broken Lullaby" with different release years or variations on the title might help.
* It's not a major release: The movie might be an independent film or a less well-known production.
To help you find the correct film, please provide:
* Any other details you remember about the movie: plot, genre, other actors/actresses you recall.
* If you remember where you saw the movie: streaming platform, theater, etc.
With more information, I can help you identify the movie and find the cast list.
