It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

This is a small, humorous movie in some ways, but it has a huge heart. What a nice experience.

This is one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.

A highly entertaining, rarely seen melodrama with a lot of grim underpinnings. Ingrid Thulin is released from a Nazi concentration camp to find that gigolo husband Maximilian Schell has shacked up with her stepdaughter. What ensues is a roundelay of lies, fraud and murder plots, mostly sprung from the demented mind of Samantha Eggar, giving a great performance as Thulin's neglected stepdaughter, a sociopath who cares only for herself. Eggar & Schell are a match made in hell, but Thulin, very much a survivor, does not fall easily for their shenanigans. Directed with a firm hand by J. Lee Thompson, who keeps the film virtually entirely indoors, adding to the feeling of claustrophobic dread. There are fine performances by the three principles and an excellent supporting role for Herbert Lom (as Thulin's wily colleague). The pre-credit sequences is astounding.

Once upon a time, before the giallos and the slasher films took over, there was an undercurrent of clever thrillers ... where you knew who had done it, but the question was could they get away with it? The earliest one I can remember is The Unsuspected with Claude Raines as a DJ with a mission ... In the '60's we had director William Castle's twisted thrillers (Homicidal is my favorite) and Bette Davis as Baby Jane and Charlotte ... then along came Return from the Ashes, at about the same time as Bunny Lake Is Missing. Ladies and gentlemen, RftA is a stunning thriller which will keep you enthralled from the expositionary opening to the wonderfully complex plot developments. Why is this not available to viewers today? This is a movie I would like to show friends. Hard to believe it was 40 + years ago I sat in a darkened theater enraptured by the clever plot with more twists and turns than you could believe. If you see this movie in any listings, record it! Ingrid Thulin, Samantha Eggar and Maximilian Schell pull out all the stops but they make you BELIEVE the lurid goings-on. Too bad movie makers can't look at these old classics and learn how to pace and plot a good thriller.

This film has haunted me right from the start of its release in 1965, thanks to the top players, the tense plot, the effective direction by J. Lee Thompson and the music from John Dankworth. But most importantly (the play of) Samantha Eggar and the melodramatic role she plays in the film are the main reason of my lasting interest in this film. The famous bathroom scenes with her are unforgettable.

This will keep you confused till the end. Written in classic theatrical play/film style of Agatha Christie. Excellent performances by Maximillian Schell and Samantha Eggar illustrates why they can be called stars. Herbert Lom is far removed from the Inspector Clouseau comedies.
