Please help find this little gem.. I saw it during pandemic outbreak 2019-20. Movie is surely from late 90’s or 2000-2008 and certainly under-rated one with no big star. I don’t recall any actor who starred but it had awesome twists and turns with some hot stuff, dark comedy and thrills.. It’s either a Hollywood or a British production, dark comic, thriller around cheating husband who goes underground and pretends killed/murdered for insurance money. In the climax, the two leading ladies kill him and together bury him in a pond/lake.. That’s how it finishes.
