Only if it's really really really what every user that would EVER use the web page will want.

I would actually like it if IMDB put focus in their search box, when I'm looking up a director of photography or such, I'm just impatience and would like to go, type, enter, read. The extra click to type is annoying. But I still don't know if they should actually implement that as I have not done a real analysis of how the broad community uses the site.
