Yes as a matter of fact, it from wikipedia so don't hold me to it, but it says
In May 2007, director Robert Rodriguez entered talks with Universal Studios and Warner Bros. to film a live action film adaptation of The Jetsons. He had also met with Universal Studios to direct a film adaptation of Land of the Lost. Rodriguez was uncertain which project he would pursue next, though the latest script draft for The Jetsons by Adam Goldberg was further along in development.
Also IMDB says there is going to be a upcoming 2009/2010 movie called The Jetsons but it doesn't go on, you know I glad you called me on this I completly forgot about his plans for Land of the lost, so thanks for jogging my memory.
