What parents need to know
Parents need to know that Closed Circuit is an English crime thriller that focuses for a while on talking and discovering information and then has a big chase-and-escape sequence at the climax. There's some fighting and a little blood when a woman is attacked and fights back. There's also a lethal explosion that kills 120 people and a car crash. "F--k" is used a few times, but, overall, language is sparse. A flashback shows kissing, and there's some flirting. One minor character is said to be a heroin dealer; he's shown suffering from using the drug. Some characters smoke cigarettes. The movie's tone/structure -- which asks audiences to think heavily during the first two-thirds and then turn off their brains during the last act -- makes it seem unlikely to appeal to a broad audience.
