Variety is reporting that Martin Lawrence and 20th Century Fox are moving forward with another Big Momma's House movie, the third in the series.  Big Momma's House 2 made almost $140 million worldwide on a $40 million budget and the first made $174 mill on a $30 mill budget, so it's not that surprising they are trying to squeeze more money out of this, despite it's tired premise and the fact Martin Lawrence hasn't been relevant in years.
