The Open Movie Database (OMDb) is a separate entity from IMDb, and its database may not be as up-to-date as IMDb's authoritative source.

To clarify, OMDb is not a layer over IMDb; instead, it is an independent service that aggregates movie information from various sources. While it provides a valuable resource for accessing movie details programmatically, users should be aware that the data might not be as real-time or comprehensive as IMDb's proprietary database.
