It has featured in a number of films since the earliest days of cinema.  The silent film "Waiting at the Church" featured a performance by Victoria as she acted out the lyrics.  Several other silent films were made to accompany recordings of the song.  Sound films which use the song include "Here Come the Huggetts", "Millions Like Us" and "I Thank You".
