How do I avoid double axis when I use movie()

The following attached file contains a code that collects frames from two subplots in a loop.

The problem is that the axis duplicates when I use the movie() command, but not during the caption of the frames.

I haven't really been able to find a solution, probably because I am fairly new to matlab :o) But if someone could help me fix it, and maybe explain how and why in a very thoroughly, you would help me a lot :)
