This movie is absolutely hilarious! There are few movies as humorous as this one, being "Mousehunt" one of those few - another 1997 motion picture.
Every minute of "Liar Liar" is pure fun and every minute means a good laughter. Many moments are hysterical! Jim Carrey is often a great comedian, but this is him at his funniest side.
The story is very funny and entertaining: Fletcher Reede, a lawyer with the habit of lying and breaking promises, suddenly sees himself forced to become honest during the next 24 hours after his son's birthday wish comes true. He doesn't understand what's happening to him and that is driving him insane... he can't tell any lies, not even write a little lie! Whenever he tries to and whenever he talks, it's a huge mess for sure! He even transforms the court room into a circus, seems to lose his mind and makes goofy faces! Incredibly hilarious!
The actors have great performances. Jim Carrey is great as Fletcher Reede, but there are other equally good actors, like Maura Tierney as Audrey Reede, Cary Elwes as Jerry and little Justin Cooper as Max (Fletcher's son). Max is also referred to as "Maximillian" and "Monster Max" by his father, who loves to do "The Claw" much for his son's delight. I know Cary Elwes from "Robin Hood: Men in Tights" and I do know that he is an English actor, but he speaks with a good American accent in this film. Some might think that Jim Carrey overacts here and that his humor is too crummy, but the energy he shows here is not something anybody could do. It requires a very energetic and patient comedian and Jim Carrey proves his talent to do so. The kid is cute. He almost looks like Sean Marshall in "Pete's Dragon", with that face and long hair.
At my point of view, "Liar Liar" has funny humor, not irritating or dirty humor. It is a modern light-hearted comedy. Its aim is purely fun at the highest level. I think it's difficult not laughing while watching this movie. Lots of very funny lines are another attribute.
Directed by Tom Shadyac, "Liar Liar" is the best thing Jim Carrey and Tom Shadyac ever did together and slightly superior than the later "Bruce Almighty".
