5/5 The Ugly Ginger Haired Kid From Harry Potter???
  by G. Browning (Sidney, Ohio USA)
I really enjoyed this movie and I think Rupert Grint did an amazing job. Ron Weasly was always my favorite of the three main Harry Potter characters and going from Harry Potter to Thunderpants was quite a transformation for Rupert. I wish that he would have made more movies during this period of his life. Dan Radcliffe steals most of the thunder in Harry Potter. I'd like to see Patrick Smash fart in Harry Potter's face....LOL. The extras on the DVD were wonderful to watch and when Alan called Patrick "Damon's Little Fart Boy" I thought I would die laughing. My kids were amazed at the familiar faces in the film..especially the girl from Chronicles Of Narnia.
I would highly recommend this movie for a good laugh.

One would think that just about all guys would love a good fart movie. Potty humor is one of the last bastions of male domination - it's where only men enjoy the subtle intricacies of a squeaker or an SBD. In Thunderpants, however, we are treated to a simply horrible movie that somehow makes fart humor uninteresting.

Essentially this movie has a hard to swallow plot about a young inventor named Alan (Rupert Grint) who uses his intestinal fortitude to help a schoolboy social leper named Patrick Smash (Bruce Cook) turn his intestinal issues into fuel for a hovercraft. When he cuts the cheese afterwards in an improved model, his dreams of being an astronaut are soon to be realized. There are twists and turns involving such nonsense as opera and government involvement, but it's really not all that important.

I suppose it could be a very cute movie for kids, and I suspect that's the target audience. For adults, however, it may as well have been named, "The ugly ginger kid from Harry Potter ruins fart humor".

Thunderpants has pungently done for fart humor what Gigli has done for comedies. I honestly know of no other way of ripping this movie. Unfortunately for all involved, this one cannot be covered up by moving a chair or blaming the dog.

5/5 Seems like it was made on a dare

This film features Harry Potter's Rupert Grint in a supporting role as Alan A. Allen, a young inventor who helps bullied outcast classmate Patrick Smash (Bruce Cook) put his flatulance problem to good use by using it to power a hovercraft. This starts Patrick on a strange path to realizing his new dream of using his gas to become an astronaut. There are several amusing detours along the way, like when he is recruited by an opera singer to fart the high notes, before Alan and Patrick team up to create a gas powered rocket to save a marooned spacecraft from the (fictionalized) U.S. space program. What makes this film so entertaining are the strong performances (including straight-faced turns from Paul Giamatti and Ned Beatty) and high production values that display an odd, endearing respect for such silly material.

Finnaly, a movie that all boys can and will relate to! My entire family laughed hysterically while at the same time learning to look at diversity in a whole new light. This film should be required curriculum for all 5th, 6th and 7th grade boys. Lets hope that filmakers agree and produce more great films for our guys!

5/5 It's a gas!

The ultimate frat party or cult film - "Thunderpants" is quickly gaining steam as the new "Airplane!" or "Rocky Horror Picture Show." I was blown away by the production values and cast considering the puerile subject matter, while repeat viewings reveal the humor to be much more nuanced than just some cheap fart jokes. And although he only has a supporting role, Rupert Grint absolutely deserves top billing. His delivery is so over-the-top it's like the rest of the cast is speaking in monotone. He doesn't just deserve an Oscar, but a Nobel Prize. Best performance ever!

Note that the domestic U.S. release shows a shorter running time than the previous Canadian import, but the film is in fact complete (the import simply counted the supplemental material in the run time). This is a delightfully cheesy film, and it would be unfortunate to cut one, let alone nine, minutes from it.
