Because it doesn't want to be confused with the groundbreaking reality show of the same name, Ron Howard's Cheaters has undergone a title change. From now on it shall be known as What You Don't Know. I guess the next line is, "I'm a cheater."

The comedy, which has an impressive cast including Vince Vaughn, Kevin James, Channing Tatum, Winona Ryder, Jennifer Connelly and Queen Latifah, was written by hot scribe of the moment Allan Loeb (Wall Street: Money Never Sleeps; the Escape from NY remake). It details what happens when a man (Vaughn) learns that his best friend's wife (Ryder) is cheating and must then navigate treacherous waters to decide what do with that knowledge.
