text: I can't understand why IMDb users would rate this movie 5.2/10? It really is great, very funny. I would strongly recommend this movie for all of you, adults, teenagers and especially children! <br /><br />The story is about a 14-year-old kid who always tell lie, at home and school. One day he had his homework of writing a 1000-word-story. But he didn't, so the teacher told him to write it and gave her in 3 hours, or he would have to go to Summer School. Yep, he wrote it in 2:45. "Big fat liar", I think it was a story of himself. On the way to the school he hit a limo of a famous Hollywood producer, and he gave him a ride. But the kid forgot the story in the limo. He told his parents and the teacher, but of course, they did not believe him. And the movie producer, he took the kid's story as his new movie, "Big fat liar". When the kid saw the trailer of the movie, he told his parents he had written it, but they didn't believe. So, he and his friend had to go to L.A to prove one thing: The truth is never overrated <br /><br />Enjoy this great movie, you won't be disappointed. Don't trust the 5.2/10 rate, it should be 9/10! Believe me! <br /><br />P/S: so sorry, my English isn't good enough to make a better comment!
