Nah, not being as hugely commercial as Windows, you need add-on software for the ultimate thumbnail porn experience. Although GraphicConverter vastly outshines what Explorer can do with thumbnails (can you view them at 400x400 in Explorer?) It does slideshows too. Finally the OS X Finder allows you to play the _entire_ movie without having to launch another app.
