Creating a successful mystery film—not a thriller, a crime drama, or something vaguely described as a "thriller", but a true detective film—has never been easier or more successful for the big screen. After all, the only reward comes at the end, when the murderer is caught and all the mystery comes together to form the whole puzzle. The focus is more on reflection and silent deduction from the action - which in the age of short attention span theater isn't really cinematic. Traditional mysteries work best on television with a series of short episodes. However, there are some signs that Hollywood is entering a new Golden Age of mystery movies.
