Richard (Ryan Gosling) and Justin (Michael Pitt) are at opposite ends of the high school feeding chain, but they are equally brilliant and equally bored by their lives. So they hatch a plan to commit the perfect murder and actually carry it out. Homicide detective Cassie Mayweather (Sandra Bullock) and her new partner Sam Kennedy (Ben Chaplin) are put on the case and Mayweather soon realizes that something is fishy. Quickly she finds herself in a dangerous game with Richard and Justin.
Murder by Numbers is nothing revolutionary, but it is a nice watch, especially for Cassie Mayweather who is a pretty great character and the generally good performances.
After the death of her abusive mother, Annie (Caity Lotz) returns to her house for the first time after many years to clean it out with her sister Nichole (Agnes Bruckner). But when Annie arrives, Nichole is gone. And there seems to be something weird going on generally in the house. As Nichole is trying to figure things out, strange things keep happening.
The Pact was creepy and very tense. Unfortunately it suffered from an incredibly weak and completely unbelievable ending.
