Try trashing iMovie's preference file, as explained in this User Tip by AppleMan1958:

Many thanks John.
Followed your advice - trashed the perference files.
But unfortunately did not fix the corrupted project in iMovies.
Do I need to do something more desparate like reinstall iMovies ??

There are two ways to save your project.
1) Use Time Machine. Attach an external hard drive to your Mac and turn on TIme Machine. It will automatically back up everything.
2) You can make a manual copy by going to the Project Library view. Select your project, and click FILE/DUPLICATE PROJECT. Give it a name like My Project Name - 2PM.
