Scraping for particular movies doesn't work

I scrape around a 300 movies so far and all worked flawlessly but some will not work. The IMDB pages seems to be the same (no particular page display).

Astro Boy 2009 and a few that I can't remember: only actors are scraping, have to rescape specific each item.

Underworld: Evolution, Zombiland, Beavis and Butt-Head do America, The Rocker, Aliens and a few more: plot and outline won't show even with a rescrape.

thx for the nice program!
