Collection of CGI-animated features following the adventures of everyone's favourite chipmunk brothers. In 'Alvin and the Chipmunks' (2007) Alvin, Simon and Theodore (voices of Justin Long, Matthew Gray Gubler and Jesse McCartney) are discovered and adopted by struggling songwriter Dave Seville (Jason Lee). When Dave finds them singing some of his songs, the foursome decide to join forces and embark on a career in the music business. When success beckons however, unscrupulous record company boss Ian Hawke (David Cross) decides that he could make a lot more money from the boys if Dave was out of the picture. In 'Alvin and the Chipmunks: The Squeakquel' (2009), when Alvin, Simon and Theodore are forced to put aside their music superstardom and go back to school, they are given the challenge of saving the school's music department by winning the $25,000 prize in a battle of the bands. But the trio unexpectedly meet their match in three singing female chipmunks known as The Chipettes: Brittany, Eleanor and Jeanette (voices of Anna Faris, Amy Poehler and Christina Applegate). Romantic and musical sparks fly in the face-off that ensues. In 'Alvin and the Chipmunks: Chipwrecked' (2011) Alvin, Simon and Theodore take to the high seas. When their luxury liner becomes grounded on a remote island during a tropical cruise, the boys soon discover their secluded paradise is not as deserted as it seems. As they struggle to contend with the heat, the insects and the close proximity to one another, the chipmunks begin to develop a few strange personality traits. In 'Alvin and the Chipmunks: Road Chip' (2015), when Dave reveals that he is travelling to Miami to propose to his girlfriend Shira (Kimberly Williams-Paisley), the three chipmunks fear for their future, especially as Shira's teenage son Miles (Josh Green) has taken an instant disliking to Dave's furry friends. As the trio put their heads together to try to break up the happy couple, they find an unlikely ally in Miles. With the common ground they share - wanting to break up the engagement - Alvin, Simon, Theodore and Miles do all they can to create a barrier between Dave and Shira.
