Christina Applegate voiced Brittany in Alvin and the Chipmunks: The Squeakquel and Alvin and the Chipmunks: Chipwrecked.

4282. Alvin Seville

Alvin is the protagonist of Alvin and the Chipmunks. His enthusiasm is boundless and his despair bottomless. The term look before you leap does not usually apply to Alvin, who is impulsive, charming, and musical. The character always seems to make up hare-brained schemes to get what his goal is at the time, whether it be trying to help his brothers, keeping Dave from figuring something out, or getting out of a sticky situation. However, Alvin seems to refer to his often illogical or crazy plans as "challenging the ordinary". Alvin's signature color is red, and he has brown eyes. On July 30, 2002, Alvin was #44 on TV Guide's list of top 50 best cartoon characters of all time.[12]
Like his brothers, he was originally voiced by Ross Bagdasarian, Sr. In the animated series and film, he was voiced by Ross Bagdasarian, Jr. Justin Long voiced Alvin in the live-action/animated film series trilogy of "Alvin and the Chipmunks".

Eleanor is much less timid than Jeanette, and is always happy to stand up to Brittany when she thinks something is not right. She is also very creative, and likes to design and create clothes/costumes. Eleanor has blonde hair with twin pigtails, brown eyes, and her signature color is spring green.

Alvin and the Chipmunks is an American animated music group created by Ross Bagdasarian, Sr. for a novelty record in 1958. The group consists of three singing animated anthropomorphic chipmunks: Alvin, the mischievous troublemaker, who quickly became the star of the group; Simon, the tall, bespectacled intellectual; and Theodore, the chubby, impressionable one. The trio is managed by their human adoptive father, David Seville. In reality, "David Seville" was Bagdasarian's stage name, and the Chipmunks themselves are named after the executives of their original record label. The characters became a success, and the singing Chipmunks and their manager were given life in several animated cartoon productions, using redrawn, anthropomorphic chipmunks, and eventually films.
The voices of the group were all performed by Bagdasarian, who sped up the playback to create high-pitched voices. This oft-used process was not entirely new to Bagdasarian, who had also used it for two previous novelty songs, including "Witch Doctor", but it was so unusual and well-executed it earned the record two Grammy Awards for engineering. Bagdasarian, performing as the Chipmunks, released a long line of albums and singles, with "The Chipmunk Song" becoming a number-one single in the United States. After Bagdasarian's death in 1972, the characters' voices were performed by Ross Bagdasarian, Jr. and Janice Karman in the subsequent incarnations of the 1980s and 1990s.
In the 2007 CGI/live-action movie adaptation and its 2009 sequel, they were voiced in dialogue by Justin Long, Matthew Gray Gubler and Jesse McCartney, respectively. Bagdasarian, Jr. and Karman continue to perform the singing voices for Alvin, Theodore and the Chipettes, but Steve Vining does Simon's singing voice. The project has earned five Grammy awards, an American Music Award, a Golden Reel Award, and two Kids' Choice Awards, and has been nominated for three Emmy awards.
A third movie installment, Alvin and the Chipmunks: Chipwrecked, was released in theaters on December 16, 2011.

2931. David "Dave" Seville

David "Dave" Seville has his patience tested on a daily basis. Not only does he juggle his professional life as the quick-tempered songwriter for the musical trio, but he's also the Chipmunks' adoptive father and confidant. While Dave struggles to remain calm and objective, Alvin often irritates him, resulting in Dave's yell, "AAAAAAALVIIIIIIIIIN!!!!!!" to which Alvin often replies with a loud "OKAY!!" Dave plays piano and the guitar. He has black hair and brown eyes. In the 2007 film Alvin and the Chipmunks, he is played by Jason Lee, the star of My Name is Earl.

He later changes his mind and welcomes them into his home, and eventually he starts to love them like his own children. However, in the 2009 sequel Alvin and the Chipmunks: The Squeakquel, Dave plays a minor role in the film, mainly due to him being in the hospital in Paris. This happened due to Alvin causing a billboard to crash into him and he is sent flying across the room and is severely injured, so he is placed in intensive care. He is rarely seen in the film. His cousin Toby acts as both a main character and the Chipmunks' temporary guardian. Dave will have a larger role in Alvin and the Chipmunks: Chip-Wrecked.

Simon Seville is an anthropomorphic chipmunk from the boy band Alvin and the Chipmunks.

According to the creators, "After that, the fan mail came a-flowin'!" In addition to having an IQ just north of Albert Einstein, Simon possesses a very dry sense of humor as well as a keen wit. Alvin exploits Simon's master mind for his crazy schemes because he is smart enough to carry them out.

He also is the tallest of the three. He plays the bass, bass clarinet, saxophone, bagpipes, tuba, and drums, among others. He is shown playing the keyboard in the original open for the 1980s series. He was also shown playing guitar in a 1980s Hardee's commercial. He is the smartest of the Chipmunks and the second oldest. He is voiced by Ross Bagdasarian. He also shares a subtle, romantic relationship with female counterpart Jeanette of the Chipettes, who is similar to him in many ways.
