Hi there,
I am looking for the title of a film released between 1930 and 1950.
I know its not Topper or Blithe Spirits but what I can remember is that the film had two ghosts/spirits (man and woman).
I remember a scene where the two "Spirits" are coming across a field as talking flames. (They also either came out of or went into a tree)
I think that the might have been related (father & daughter?). That's about all I have to go on. Any help is very grateful.
Kind regards

I Married a Witch (1942)
Starring Fredric March, Veronica Lake, Cecil Kellaway, Susan Hayward
IMDb synopsis:
In 1672, two witches~Jennifer and her father Daniel~were burned by Puritan Jonathan Wooley. In revenge, Jennifer cursed all future generations of the Wooley family, that the sons will always marry the wrong women and be miserable. In the 20th century, a bolt of lightning frees Jennifer and her father from the tree that had kept their souls imprisoned. Jennifer assumes corporeal form and decides to make up-and-coming politician Wallace Wooley, then unhappily engaged, even more miserable by getting him to fall in love with her before his wedding. Wallace is a straight arrow, though, and Jennifer has to resort to a love potion. As we all know, love potions tend to backfire, with comedic results.
