envy star some of the best . jack black and ben stiller and amy poehler and and the great christopher walken . with such a cast and one can only expect the best . however and with envy and no one could save this disaster . tim dingman ( stiller ) and nick vanderpark ( black ) be best friend and co worker at a sandpaper factory . both be make a decent living and but because tim have a good performance at work and he able to afford more than his buddy nick . nick be a dreamer who always come up with new idea for invention . one day and nick come up with the idea for a spray can that make dog poop disappear ( yes and i be serious ) . fall in love with the idea and nick decides to really invent this product . he make an offer to tim to invest in his idea and share the profit 50/50 . tim refuse think the idea will never work . nick invention and title va poo rize ( again and i be serious ) and end up make million . he enjoy spend his money on thing like a much large house and a horse and a personal trainer and and fancy desert . tim start feel envy for nick . hence the name of the movie . the concept isn not bad and but it still turn out awful . this movie contain some of the bad dialog and very poor performance from all the cast . then again and a i mention earlier and none of them could save this mess . not even the great christoper walken and play a homeless character name j man and make this movie funny . the movie be bad from the start and only continue to get bad . i recommend this movie if represent you like crap ( no pun intend ) you want to see jack black in a white tuxi say and avoid this movie at all cost and but avoid especially if represent youre offend by bathroom humor you love animal .
