A couple of new movie posters have turned up recently, most notably, for the following two movies — Sunshine and Die Hard 4.0.  Those, and a few other interesting links are listed below —

• Filmz.ru has a large-resolution version of the first teaser poster for Die Hard 4.0.  Apparently, this film is going to be titled Live Free or Die Hard in the US only, and in other countries, it's going to be called Die Hard 4.0.
• JoBlo has a look at the US poster for Sunshine here.  It is pretty interesting to look at, but somehow seems like the artwork for a direct-to-DVD release!
• The UK version of the Sunshine poster is available (in both one-sheet and quad formats) over here, at SolaceinCinema.  This is far more impressive than the US poster (nice use of Helvetica here!).
• Speaking of Helvetica, there is actually a documentary film called Helvetica that is going to be released soon.  The release of the film commemorates the 50th anniversary of this very elegant typeface.  Here is the official site for the film (with info, a trailer and some clips), and here is an article about the film at SolaceinCinema.
• The same site has another interesting article about the company (called Foreign Office) that created the fictional advertising and other graphics used in the movie Children of Men.  At their site, there is an MOV clip that shows off the work they did, which is pretty amazing!  Here is a direct link to the MOV file (right-click and "Save As..."), which is around 14 MB in size.
• IMPAwards has got a look at a banner for Grindhouse as well.

Seeing as how this post is largely about movie posters, have a look at the Wikipedia article, for more information about different poster formats.
