The Last Request is a low budget indie horror that was written by and stars Dallas Ryan and Ryan Vania, with Dallas also directing. This was an odd film that became quite experimental at times. While it is a bit rough around the edges the general idea behind it was decent enough.
John (Ryan) and his brother, Michael (Vania) wake up in a strange house with no recollection of how they got there. John soon discovers a letter which informs the siblings that Michael's daughter has been kidnapped, and that unless they play a series of cruel games she will be killed. They are also told that any attempt to leave the house will also result in the girl's death. Bizarrely, they have also been given a small dog which they are instructed they must take care of.
This is a low-fi movie in which everything is suggested and barely anything is actually shown. The brothers are on board to do what the letter instructs without any real evidence to support the claims. It starts off innocently enough with them told a watch they find has been fitted with a bomb. As the day goes on the two get told to do more and more sadistic things to each other. All of this occurs off camera, when trauma does happen this too is all just suggested with no blood or anything. This is working to the limitations of the budget but it also created a feeling of low stakes. The fact that their kidnapper chose to speak to them via printed letters hidden around the house fits this weird low stakes situation.
