Movieclips has one of the most comprehensive collections available on the Web — and there's no need to wade through duplicates. You can search by film title, character name, actor or keyword. Searching for "fight" yields an interesting library of Rocky moments, period sword duels and even a pillow battle or two, whereas "first kiss" brings up famous on-screen smooches from the likes of Romeo, Scarlett O'Hara and the cast of Grease. But Movieclips is a quintessential film index with a twist. With a built-in editing tool, users can create their own video mashups with relative ease. We opted for a Wizard of Oz–Inception mashup — watch it here — and were able to create the entire thing in less than 10 minutes.
