Todd Phillips has found the perfect duo for his upcoming bachelor-party comedy Hangover. According to The Hollywood Reporter, both Bradley Cooper and Ed Helms have signed onto the illustriously vulgar project.

The plot of this raucous laugher revolves around three friends that lose the groom in Las Vegas during their bachelor shenanigans. At this time, the third friend has yet to be cast.

The film is quickly moving towards actual production, and will most likely see the light of day sometime in the spring of 2009.
