not to bust your bubble, but not really. You may be able to spy a slight glimps of them over the trees behind and to the left of you if you are sitting on the top row of bleachers at the movies.
If you want to sneak out of the movie before it's over and make your way to the marina you might get a better look, but it will still be pretty obstructed by the tree filled island in the middle of bay lake. (sorry - forgetting the name of that island)
The best view we have ever had of FITS fireworks (and not actually being in MK) is a toss up between the observation deck at the top of the contenmporary (do they still let guests up there who don't have a ressie at that restaurant?) OR on the boat between FW and MK. (if you are lucky to time your boat ride JUST RIGHT)
