Two self-confessed Cardiff 'film geeks' are holding a 46-hour 'Bondathon' - watching every Bond film made to raise money for charity.
The challenge is to watch all 23 Bond films over a three-day period, starting with Dr.No at midnight on Friday and culminating with a cinema screening of Skyfall on Sunday evening.
Rhys Jones and Terrence Edwards will load their first DVD at midnight and will write a retrospective blog post and podcast about each of the films to share with other James Bond fans around the world.
The two Cardiff films buffs were recently nominated for their blog: thewatchersfilmshowblog in a Welsh blogging competition.
The pair are hoping to raise money for Cancer Research Wales. It's something close to both of their hearts, as both of their fathers are currently undergoing treatment for cancer.
So far their efforts have raised around £250 for the charity.
