卡尔是个有着怪脾气老头，胖得像球一样小孩小罗看着又傻乎乎。《飞屋》主线并不复杂，但起承转合有自己独到的地方，比如，影片开头用了近20分钟来记述卡尔和爱丽是如何相识、相爱、相守到老的过程，除了表现爱丽和卡尔个性的童年时期，几乎全无对白，就是那样接近完美的“陪着你慢慢变老的过程”，不需要言语煽动，情绪就无声无息地上来了。而创作者没有打一枪换一个地方，这段看似与冒险过程无关的回忆，成为了卡尔制造飞屋、甚至重塑自我的最大动力，也在几个关键节点反复用力推进情节转折。主角的设计也有小惊喜，卡尔不是慈眉善目的老爷爷，他多少有些怪脾气，为了保护爱妻遗物还会有暴力倾向，小孩小罗胖得像球一样，看着傻乎乎，废话还很多，这些与保守的审美观有矛盾的细节一再爆发出喜剧火花，另外，皮克斯招牌的抢眼配角继续爆发搞笑功力，会说话的狗这个族群的设计最能体现皮克斯的小机灵。
英文影评：
UP, Pixar's latest animated feature, is just delightful. But how do you go about extolling the movie's virtues without giving away its surprises? Like the kid at the beginning of the movie, you don't try to conquer the immovable force; you work around it.
The one clue I can give away – because it's the movie's heavily hyped premise – is that Carl Fredrickson, a gruffy old widower (voiced with gruffy old charm by Ed Asner), miraculously inflates enough balloons to use his house as an aircraft. Soon, he finds himself reluctantly sharing his ride with a short-attention-spanned kid named Russell.
I'll also mention a couple of other items that can gauge your potential interest in the movie. One is a gag that is a take-off on a famous painting – perhaps too inside of an inside joke, but typical of Pixar's cheery attempts to appeal to viewers of all ages.
Also, part of the plot involves Carl's long-held wish to meet a Lindbergh-type adventurer named Charles Muntz (Christopher Plummer!). This is another in-joke that's even vaguer than the first one. Cartoon historians know that Walt Disney started in the cartoon biz by creating Oswald the Rabbit for producer Charles Mintz, who then greedily stole the rights to Disney's creation. This gives you a pretty good idea where the ostensible hero Muntz stands in the scheme of things.
Beyond that, I can only offer you some enticing clues about the characters. There's a dog who's the leader of his pack and in menacing beyond measure, until he opens his mouth and gets one of the movie's biggest laughs. There's a huge, awkward bird that is a big laugh-getter at first. Then she becomes a real enough character that – at least in the audience I was in – when she's injured, she elicits screams of fright worthy of Bambi's late mother.
There's surprising, heartfelt emotion, vivid imagery (you can almost touch the landscapes and skies), and a music score by Michael Giacchino that's practically a character in the movie – particularly in a thoughtful montage that takes Carl from childhood to widowhood.
There aren't many (or at least not enough) live-action movies that are engrossing as this cartoon. Pixar Studios has gotten to be one of those movie icons that shouldn't even have to deliver a premise to get funded anymore. The moneymen should just shut up, hand over the money, and trust they'll get a product that will appeal to everyone.
UP is only the second Pixar feature to get a PG rating, only for mildly intense imagery and action – nothing off-color in the least. Again, if you can handle "Bambi," this film should be a breeze.
