Satan's Little Helper is a horror-comedy film released in 2004. The movie takes place on Halloween day as a young boy named Douglas (played by Alexander Brickel) is obsessed with a video game called Satan's Little Helper. The game features a character named Satan who goes around killing people.
Douglas is excited to go trick-or-treating and dress up as Satan's Little Helper. While out collecting candy, he comes across a man in a devil costume who he believes to be the real Satan. The man, who is actually a serial killer (played by Katheryn Winnick), takes advantage of Douglas's naivety and convinces him to help him commit murders throughout the night.
Unbeknownst to Douglas, the killer is using him as a pawn in her twisted game of murder and mayhem. As the night progresses, Douglas starts to realize that something is not right and becomes increasingly scared of the "real" Satan.
The film switches back and forth between horror and comedy, with Douglas's family members (played by Amanda Plummer and Stephen Graham) providing some much-needed comic relief. The movie also features a surprise twist ending that is sure to shock audiences.
Overall, Satan's Little Helper is a darkly comedic horror film that mixes innocent fun with pure evil. The film's unique premise, witty dialogue, and gruesome kills make it a must-see for fans of the horror genre.
