Select the timeline on your movie project and then press the \ key (above the Enter key on your keyboard). This sets your timeline to display your entire movie. Is your movie two minutes long or is the timeline displaying a much longer timeline?
If the program is showing your timeline way beyond the end of your movie, you have some stray frames or clips out on our timeline, beyond the end of your movie, making the program think your movie is longer than it is.
In Expert view, drag over that portion of your timeline to select these stray frames and delete them. When you think you've got them all, again press the \ key. Keep doing this until this view shows only your two minute movie.
