This movie was made to answer a burning question: What if Jim Carrey starred in another movie? Would it make 300 million dollars?
The answer, of course, was yes.
Secondarily, the movie asked another question: What would life be like if you couldn't tell a lie? To answer that question, the movie introduces us to Jim Carrey as Fletcher Reede, a cynical and unethical lawyer who Doesn't Spend Enough Time with His Son. His ex-wife Audrey (Maura Tierney) is at her wits' end with Fletcher's flakiness and dishonesty, and she wants to move away to Boston with her fiancé Jerry (Cary Elwes) and take young Max (not portrayed by Alex D. Linz) along.
On Max's fifth birthday, after Fletcher breaks yet another promise to visit, Max makes a wish that for 24 hours Fletcher will be incapable of lying. Remarkably, the wish comes true, but fortunately Fletcher retains his ability to mug to the camera and say wacky catchphrases. But if Fletcher is forced to speak the truth, how will he go about his job of unscrupulously flouting sundry rules of professional responsibility?
After a series of increasingly zany setbacks, Fletcher discovers a convenient technicality that enables his client to win her case without lying. In the process, he discovers the true meaning of fatherhood, and resolves to stop Audrey and Max from moving to Boston. He exploits the laxity of pre-9/11 airport security to hijack a mobile stairway and drive it down a runway at the takeoff speed of a 737. (Those were the good old days, huh?) This extreme deviant behavior is exactly what was needed to convince Audrey that Fletcher can be a decent father, so she decides to stay in L.A.
This is a great example of a movie that starts with a clever premise and then actually makes it work. The strategy seems to have been to stick Jim Carrey into every situation where a normal person would feel compelled to lie: A one-night stand, a traffic stop, a meeting with your boss, a phone call from your mother, and of course, identifying the color of a pen. These scenes are funny, and the movie wisely avoids doing much else. I shudder to think what might have been if they had made the kid anything other than the plot device he is. Because the jokes work well, the moral character development scenes are easy to swallow. (And the line "I hold myself in contempt" is a very enjoyable play on words.)
Finally, also deserving of mention is the fact that this is one of many movies that has forced poor Cary Elwes to struggle with an American accent. Why couldn't Jerry have been English?
