A sequel has been decided so we may expect Madasgascar 2 in November 2008. According to an interview given by Ben Stiller, all the animals from the first film get off Madagascar in the downed airplane stuck in the trees from the first movie. They crash in Africa, and Stiller's lion character Alex gets to know his relatives.
All our friend from the first installement of Madagascar (Alex the Lion, Melman the Giraffe, Gloria the Hippopotamus , the Zebra, Maurice the Aye-aye, Mort the Goodman's Mouse Lemur) should be back in this sequel.
I wonder if the second Madagascar movie will try to revive some old hit music song like in the first one with:
Madagascar - I Like To Move It!
Hurrah for Madagascar!
