The film features Ben Stiller, Chris Rock, David Schwimmer, Jada Pinkett Smith, Sacha Baron Cohen, Cedric the Entertainer, Andy Richter, Elisa Gabrielli, McGrath, Chris Miller, Christopher Knights, and Conrad Vernon reprising their voice acting roles from the first film, joined by new cast members Bernie Mac, Alec Baldwin, Sherri Shepherd, and will.i.am, as well as voice acting veteran John DiMaggio.
In the film, the main characters, a party of animals from the Central Park Zoo whose adventures have taken them to Madagascar find themselves in the African savannas, where they meet others of their species and where Alex the lion reunites with his parents.
Rival lion Makunga challenges Zuba for the title of alpha, but during their fight, Alakay is captured by poachers and put in a crate.
The crate falls into the ocean and drifts to New York City, where Alakay is renamed Alex, grows up at the Central Park Zoo, and meets his lifelong best friends: Marty, Melman, and Gloria.
Years later, following their adventure in Madagascar,[b] Alex, Marty, Melman and Gloria, along with Skipper, Kowalski, Rico and Private, the penguins, and Mason and Phil, the chimpanzees, prepare to return to New York aboard a battered airplane piloted by the penguins, accompanied by King Julien, Maurice and Mort.
Nana, a tough old woman who attacked Alex in Grand Central Station,[b] takes charge of the stranded tourists and helps them survive in the wilderness for the time being.
It is actually a fighting contest, and Makunga tricks him into choosing the strongest lion as his opponent, resulting in Alex's humiliating defeat.
Marty, Melman, Gloria, the penguins, and the chimpanzees arrive in the repaired airplane and help Alex destroy the dam, restoring the water.
The website's consensus reads, "Madagascar: Escape 2 Africa is an improvement on the original, with more fleshed-out characters, crisper animation and more consistent humor.
"[16] Joe Morgenstern of The Wall Street Journal wrote: "The roots are shallow, but the sequel is good-natured, high-spirited and perfectly enjoyable if you take it for what it is.
[18] Kelly Jane Torrance of The Washington Times gave the film 3/5 stars, writing that it "might not offer audiences cutting-edge animation or a particularly original story", but added: "It still has a lot going for it, though: foot-tapping music, laughs for young and old and the prodigious talents of Sacha Baron Cohen.
"[19] Shubra Gupta of The Indian Express wrote that the film was "as spunky, witty and funny" as its predecessor, and praised the animation and characters, but criticized the story for "[taking] the same course as The Lion King, with a detour towards Shrek thrown in.
"[20] Carrie Rickey of The Philadelphia Inquirer gave the film 2/4 stars and wrote: "Take the flat tire that was Madagascar.
"[21] Peter Bradshaw of The Guardian gave the film 2/5 stars, describing it as "a frankly disappointing piece of opportunism, with a non-plot which shamelessly rips off The Lion King.
"[22] Anthony Quinn of The Independent also gave the film 2/5 stars, writing: "The visual invention and draughtsmanship are mightily impressive; a shame the drama's a bit of a bore.
