Jim Carrey plays a lawyer whose son, played by Justin Cooper, wishes his dad can't tell a lie for a whole day in Liar, Liar. Audience reaction was swift and hostile. Liar, Liar already has a problem in that general laughter drowns out several lines.
Work always comes first.
He wants to be a partner in his law firm, and he works like a madman. It's a silly premise brought to life by a silly script. Director Tom Shadyac has Carrey behaving, for perhaps the first time ever, as if he's in the same movie as everyone else. It is to laugh.
