Common Sense Note
Parents need to know that even though it has one great plot twist, Unknown will disappoint those who liked star Liam Neeson's last thriller, Taken. It has quite a lot of violence, mostly centered around big, brawling fistfights, car chases and crashes, and explosions. Brief flashback scenes show a married couple kissing and making love (no nudity). Language is infrequent (a couple of uses of "s--t" is the worst of it), and while the bad guys use an array of mysterious lethal/knockout drugs, there are no "real" drugs. Overall, the biggest problem is that it's slow and uninvolving, with a downer of a message ("you can't trust anyone") and a main character who isn't particularly sympathetic or admirable.
The main character and his wife are shown kissing and making love in flashbacks. No nudity, but viewers hear moaning and heavy breathing.
Several car chases and crashes, several fistfights, and a little blood. Guns are drawn and fired. A man murders a woman by twisting and snapping her neck. A woman is knocked unconscious, a character is zapped with a Taser, and a character is sliced open with broken glass. There are huge explosions, with fatalities. Characters frequently argue with and confront one another.
Language includes infrequent use of "s--t," "ass," "bitch," "hell," "damn," "a--hole," "oh my God," and both "Jesus" and "Christ" used as exclamations.
The movie's message is a downer: You may believe one thing about yourself, but if enough people tell you otherwise, it may not be true. You can't trust anyone, and if you do, your life -- and the lives of your friends -- could be in danger.
Drugs / Tobacco /
The main character gets some sort of knockout drug while in the hospital. The villains have a deadly drug that kills its victim in seconds. One character takes cyanide.
