Oh good, there will be a third one (He writes sarcastically!)!!

Santa Clause Meets Jack Frost, Comes Up Short
Martin Short will be taking his turn as the bad-guy for his next role, in Walt Disney Pictures’ The Santa Clause 3. Variety is reporting Short will play none other than Jack Frost, who has his icy sights set out to take over Christmas from Santa Clause, since Christmas falls within his winter domain.
Tim Allen will be returning for his seasonal split personality role, as Scott Calvin and The Santa Clause himself. Allen will have a bit more work on his cookie-plate this time around as Calvin must work to keep Frost away from Christmas, all while trying to maintain a happy regular family life at home.
Michael Lembeck, who directed Tim Allen in the first two Santa Clause films, is also coming back for the third chapter of the Santa-saga, which starts shooting November 14th, for release Christmas 2006.
