The full trailer for 500 Days of Summer has arrived online and it's looking better than the teaser, giving us a lot more information on what the story is actually about.

Add to that there's a promotional teaser for Entertainment Tonight's show which will give us more footage and information on Michael Mann's next film, Public Enemies, and this is much better quality than the last.

500 Days of Summer stars Zooey Deschanel as a woman who doesn't believe that love exists and Joseph Gordon-Levitt who is a man with a hugely romantic heart that falls for her. The story is simple enough, and the film looks a lot better for this new trailer which you can see over at Yahoo Movies [Flash:480p:720p:1080p].

Meanwhile IESB have found a much better copy of an Entertainment Tonight promotional teaser for their upcoming show which will feature some footage from the new Michael Mann film Public Enemies which stars a whole host of stars in this Feds versus the Gangsters film. Boy is it looking good.

What will be interesting about this is seeing what Michael Mann does with this era, and whether we'll see something like Heat brought back in time, or a more stylish Untouchables, or whether we see something exciting and new from Mann. I'm with the latter so far, have a look and see if you think that too.
