From IMDb (Melancholic_Swinton):
I (hesitantly) emailed Jay Anania (the film’s director), just telling him I was really anticipating the film etc. and if there was any new information. He very kindly and courteously responded confirming that it was now called The Letter (and would be distributed under that name), and that it is to be distributed by Wrekin Hill Entertainment (a sub-company of Lionsgate). Even he’s not sure when the film’s release date is, but said that he believes Wrekin Hill has contractually committed to release it this year, adding that it will most likely have a ‘small theatrical’ release and then ‘different VOD and dvd stuff’.
