Not in Kansas anymore
Movieclips.com is an interesting new website, providing an alternative to YouTube for watching film clips. The site is in 'beta' mode and I have experienced some problems viewing clips, but it is still worth a look.
One nice feature is that it is totally legal – they have apparently worked with Hollywood studios to bring the site to fruition. Another feature is that you can browse the content – by movie, actor, genre, occasion, action, mood, character, theme, setting and prop; and you can also browse through a selection of iconic clips.
I also like the way that you can search for a particular phrase (in the dialogue) – the clips below are the two results for the phrase, “not in Kansas anymore.”
