According to IMDbPro, Robert Pattinson “The Lost City of Z” will be released in UK cinemas on 24 March 2017.  Nothing is listed under the British Board of Film Classification as yet, other than the trailer has been given a classification and it appears that it may be released tomorrow, Friday 13 January 2017.  At the moment, Studio Canal UK still has no date listed either, so I’ll just post this and add the disclaimer that “dates are subject to change”, but for now you might want to pencil it in.
