It seems to be a good time to be a fan of film. This upcoming movie season is loaded with some pretty promising stuff. Here's my shortlist (which is actually kind of long... which I guess is evidence of the collective quality of the upcoming movies):

The Darjeeling Limited
Once *
Sunshine
Day Night Day Night
This is England
Civic Duty ?
Right At Your Door
3:10 to Yuma
The Signal ?
Rescue Dawn
Gone Baby Gone ?
No Country for Old Men
Rendition
Shoot 'Em Up ?
1-18-08 *
A Mighty Heart
Rocket Science
30 Days of Night *
Across the Universe
Vantage Point ?
Interview
Sleuth ?
Ghosts of Cite Soleil
Self Medicated
American Gangster
The Assassination of Jesse James by the Coward Robert Ford ?
I Am Legend ?
The 11th Hour *
Michael Clayton
Dedication *

Legend:
* = High Potential Cheese Factor
? = Could turn out bad. The trailer looked decent, and there is some upside, but I take no responsibility should the resulting movie be a total pile.

My top 3 most promising...
Into The Wild (read the book first dammit)
Lions For Lambs
No End In Sight

Go to the Apple Movie Trailer Site to judge for yourself. I've listed them pretty much in the order they appear in the studio view.
