Currently Being ModeratedOct 25, 2010 1:18 PM (in response to teutates74)Hi There
As its only heavy and serious users who are getting this problem ... like wot I am .. here's what I did.
Go to Users / iMovie and then go to the Projects folder. Pull out the folder that is causing the problem then let iMovie 11 import the remainder of your projects then pull the folder back in.
Chances are it will stall again at that Project.
If it does ... pull it on to the desktop again like you did above.
Now look in it .. I found about sixty odd files with about only ten with image files .. the rest were all zero k empties ... I deleted all the stuff with zero k and only the stuff with little images.
Pulled it back in .. et voila .. it works!
Hope that helps ... BUT now I have to work out why many of my past projects have error triangles and audio that doesnt play ... in't life grand? And no it doesn't JUST WORK Apple ...

Currently Being ModeratedOct 26, 2010 9:23 AM (in response to BruceEBonus)I did what you said and it worked. Although some of the files were not 0kb they were very small files, no larger than 55kb and I deleted them and that was the trick.

Currently Being ModeratedOct 30, 2010 4:12 AM (in response to teutates74)I am having the exact same issue, but all of my thumbnails are being generated from iPhoto where I have maybe around 30gb of digital camera clips in with my photos.
I am finding that I need to force quit iMovie on every occasion that I open it when I have iPhoto open at the same time...
All of this with a brand new iMac 27''

Currently Being ModeratedJan 22, 2011 6:16 AM (in response to jmunro21)I had this very same problem, started up iMovie and it wouldn't generate thumbnails. I, however, have two external hard drives where I store photos on Aperture and film clips. I switched off the external drives and re-launched iMovie and it worked immediately, generated thumbnails immediately. When I switched on one hard drive with the Aperture library on it it also worked immediately but not with the two hard drives in tandem.

Currently Being ModeratedFeb 3, 2011 3:40 PM (in response to john payne)I've tried everything listed here, and no success. It keeps hunting for two .mov files that don't exist, and thus I cannot find them. Nor can iPhoto find them (I've checked every movie listed in iPhoto).
I have to force-quit iMovie 11 every time.
I'm now at the stage of totally rebuilding iPhoto from scratch, and upgrading all of the internal data that it keeps (even though the upgrade worked fine for iPhoto).
Incidentally, I've no movie files in my Movies folder at all, nor any projects. Starting from a blank sheet, other than what sits in iPhoto (hence my thought that rebuilding iPhoto was the way to go).
Will report back when iPhoto is rebuilt.MacBook Pro 2.4 GHz Intel Core 2 Duo, Mac OS X (10.6.5), 4GB RAM
Currently Being ModeratedFeb 3, 2011 4:40 PM (in response to ivanovitch)Great: I've now transferred the problem to iPhoto: it cannot find three movies, yet I cannot find which movies they are meant to be (they aren't on my computer in any event, and I cannot find the reference in iPhoto, grumble grumble...). It also takes forever to search the entire machine for each missing file.MacBook Pro 2.4 GHz Intel Core 2 Duo, Mac OS X (10.6.5), 4GB RAM

I exerienced the same thing. I found that it was having trouble generating thumbnails for very short movies that had little to no changes from frame to frame (e.g. a 3 frame movie where every frame was the same).
I Don't have a fix, but to prevent it from happening try to import those files.
To stop iMovie from trying to create the thumbnails I had to:
1. Force quit iMovie
2. Navigate to ~/Movies/iMovie Events/<Your Event>/Thumbnails/
3. Find the file(s) that don't have thumbnail (the file will be there, but won't have preview image in finder) and Delete file(s)
4. Navigate up one directory to ~/Movies/iMovie Events/<Your Event>/ and delete the original file with same name as troublesome thumb.
5. Restart iMovie.
hope this helps.

Solution for Me: Follow all the above and then open and leave open, iPhoto before opening iMovie.
Background: Attempted to open iMovie-11 after a three week break, only to see it freeze after authorising it to make new Thumbnails of the videos in iPhoto. Allowed 15mins in case it was actually working behind the scenes before 'force-quitting.'
The pattern was repeated many times despite meticulously following all the advice on this thread and several others around the forum. Nothing seemed to fix the snag with many valuable hours wasted.
Usually when solving issues, I close all programmes not directly related to the problem app. (I resaon that memory and resources are better 'concentrated') I recalled that iMovie initially grounded when trying to make thumbnails of my iPhoto videos I think after an update. So out of curiosity I opened iPhoto and iMovie loaded safely. iMovie did stumble one more time after replacing the suspected errant folders from my desktop into the Users / iMovie folder, (as in Bruce EBonus excellent suggestion above) but another 'repair permissions' and re-boot and everything has been fine since.
I hope this helps anyone suffering the same issue.
