Very cool trailer for Boyle's '127 Hours' debuts

The first trailer for Danny Boyle's next adventure "127 Hours" is now online, so check it out after the jump. It really delivers the goods, and it already has me hooked more than "Slumdog Millionaire."

"127 Hours" is based on the true story of Aron Ralston, who amputated his own arm and rescued himself after he got trapped under a boulder for almost five days during a big climb in Utah in 2003.

Simon Beaufoy, who also wrote Boyle's "Slumdog Millionaire," penned the script. James Franco, Kate Mara and Amber Tamblyn star. The film hits theaters Nov. 5, 2010. Awesome trailer indeed!
