Rosencrantz and Guildenstern Are Undead (2009)

Julian Marsh is an out of work ladies' man who lands a job directing a bizarre adaptation of Hamlet. After casting his best friend and his ex-girlfriend in the show, Julian finds himself in the middle of a two thousand year old conspiracy that explains the connection between Shakespeare, the Holy Grail and some seriously sexy vampires. It turns out that the play was actually written by a master vampire name Theo Horace and it's up to Julian to recover the Grail in order to reverse the vampire's curse...If only being undead wasn't so much God-damned fun!
