Quite enjoyable omnibus of three murder tales:
"In the Picture" is the most overtly supernatural, about a painting in an art gallery whose inhabitants have a peculiar existence of their own. The nasty ending would have made this an excellent episode of Thriller.
"You Killed Elizabeth" is a fairly by the book murder mystery with a nice ending. It is spoiled mainly by the fact that both the victims are rotters who rather deserve what they get.
"Lord Mountdrago" is the most notable of the three, with Welles in fine form as the title character, a larger than life politician tortured by dreams where his main rival appears. It further appears his rival (Badel) knows what is going on in these dreams. The scene where Welles breaks down and begins singing 'Daisy Bell" is startling, and the imagery of a supremely logical personage having a literal short-circuit must have been noted by Stanley Kubrick, who used the same device fifteen years later.
Note: This was filmed in summer 1953, and apparently released in May 1955. When it was reissued in February 1958, British Lion insisted it was not a re-issue, but rather a re-edited and shortened version, and that the original was never released. Thus it is rather difficult to give a definitive date of release.
