The mov files are already compressed which is why there is very little room for more compression by zipping the file. Movies are big. Consider the size of a DVD movie which is even lower resolution then that produced by the D7000.
If you need to send it to someone else, you can upload to y-tube or something and give out the link.

If you want to compress the movie just as it is, I don't think you'll have much luck. You might shave off a couple of percent more by fooling around with advanced lossless compressors, but I don't think there is anything that will really compress it much.
To really reduce the size you will have to transcode the movie with output settings that use:
1) a more efficient encoding type, or 2) lower quality settings, or 3) a slower frame rate, or 4) a smaller frame size, or 5) some combination of the above.
(Of course, if you are going to end up with a smaller frame size you might consider selecting a smaller size in the movie settings when shooting.)
You can get yourself a copy of Quicktime 7 Pro from Apple for Mac or Windows for $30. That will let you export your movie with whatever settings you like.
