Alvin And The Chipmunks
The tree that the chipmunks Alvin (voiced by Justin Long), Simon (voiced by Matthew Gray Gubler) and Theodore (voiced by Jesse McCartney) live in is cut down and driven to Los Angeles to become a Christmas tree. Once in LA, the Chipmunks meet struggling songwriter David "Dave" Seville (Jason Lee) who had his latest song rejected by JETT Records executive Ian Hawke (David Cross), who was Dave's college roommate. Dave once had a relationship with his beautiful next door neighbor, Claire (Cameron Richardson). She broke up with him because she felt he was too busy and irresponsible and he didn't have any time for her.
After winding up at Dave's interview, they hop into his basket and follow him home. Once at home, he discovers the Chipmunks, and is accidentally knocked unconscious. Upon waking, he kicks them out until hearing them sing. Dave then makes a deal with them- they sing the songs he writes, and he provides shelter for them. However, all does not go well, as Dave's job presentation is ruined by their coloring on it, and when Alvin tries to set the mood for his dinner with Claire, things become weird and she rejects him after he tells her his life has been ruined by them. To make it up to Dave, Alvin, Simon and Theodore go to Ian.
Once the Chipmunks sing Dave's song to Ian, Ian instantly signs them to the label. After a few singles, the Chipmunks become wildly popular. When Dave expresses concern for their well-being and insists that the Chipmunks are "kids" who don't need so much craziness in their lives, Ian convinces the Chipmunks that Dave is holding them back.
Eventually, Dave and the Chipmunks have an argument and, in anger, Dave tells them that if they like "Uncle Ian" so much, they should just go live with him. They become enchanted with Ian at first, but once they set off on a coast-to-coast tour, Ian takes advantage of their naivete, changing their image and working them constantly. Meanwhile, Dave misses the chipmunks and he wishes they would come back home. He calls Ian to see if he can talk to the them but Ian refuses, and then conceals Dave's motives from the boys.
Later, the Chipmunks are wearing out, and it is all over the news. Dave, infuriated by what Ian has done to the three, decides to take matters into his own hands by infiltrating their concert at the Los Angeles Orpheum Theater.
Immediately before a big concert, a doctor says that the Chipmunks can't sing because their voices have given out. Ian doesn't want to hand out refunds and orders the Chipmunks to lip sync. With Claire's help, Dave sneaks into the concert, but is grabbed by the security guards. When the Chipmunks see Dave being taken away, they realize they've been tricked, decide that they've had enough of Ian, reveal that they were lip-syncing and run amok, ruining the concert. They are soon caught by Ian just when Dave is about to rescue them. He locks them up in a cage. Dave tries to convince Ian to let the boys go but Ian refuses. Ian then leaves in his limo with the boys and Dave chases them but the boys have already escaped to Dave's car. Dave immediately pulls over and admits that he loves them like his own family. Meanwhile, Ian looks in the cage and sees the boys have replaced themselves with merchandising dolls.
Sometime later, the boys are now part of the family, and they invite Claire over for dinner. Alvin accidentally shorts out the circuits trying to open champagne. Dave decides not to say it, but it causes a blackout in the kitchen. Dave decides to say it, and receives his trademark yell "ALLLLVINNN!!", and Alvin responds with "Okay!"
