When Fletcher Reede’s (Jim Carrey) young son Max (Justin Cooper) wishes for his father to tell the truth for a day, little does he know the havoc that he will wreak on his father’s life. Being a lawyer and a habitual liar (or is that redundant?), Fletcher finds it exceedingly difficult to go about his daily business without being able to deceive, embellish or outright lie. This jeopardizes the civil court case he is arguing on behalf of a beautiful woman (Jennifer Tilly). If he can get through the next 24 hours without losing his job and, more importantly, his son, Fletcher will have learned some important lessons about life.
The first half of "Liar Liar" is a comedic roller coaster where the implications of being forced to tell the truth are explored in detail. The second half of the film focuses on Fletcher’s attempt to win the trial and make amends with his son and, to a lesser extent, his ex-wife. It is this half of the film which stumbles. What was turning out to be one of the most consistently amusing comedies in recent years becomes instead a sticky-sweet family film. But don’t think this implies that "Liar Liar" is suitable for all ages, because its not. Sexual situations and innuendo are rampant. Even still, the film may be worth seeing just for the endless stream of laughs that are generated by the film’s first half.
