What are some good "Who done it" movies?

As the title says: What are some good "Who done it" movies?I really enjoy horror, thrillers and criminal movies, especially when it comes to a wide variety of characters, all with unique personalities. Figuring out who commited a murder, while being surprised with a great twist.Do you guys have any suggestions to what are some of the better movies like this?Also, no need for them to be one of the above genres. I prefer those, but wouldn't mind something else with the same shtick.Thank you!EDIT: Thanks again to everyone for your suggestions! This is gonna be a wild and awesome ride, checking those movies out. :D via /r/movies https://ift.tt/2zG3BMG
