Dr. Li and the Mummy (1940)

Sinopsis

While outside in a hotel garden at night, Miss Tang runs into a vampire. Mr. Li tries to find out if it's real or not. It may have something to do with the hotel grounds being a former gold mine. After its theatrical release, this has yet to be released again in any format anywhere. It's believed to be the first film ever to contain the jiangshi, or hopping vampire.
