I love Hugh Grant. I don't care if he plays himself in every movie because I think he's completely charming and divine. I love Julia Roberts; she has the most beautiful smile. And, I found this movie hilarious. Watch the part where Hugh interviews her as a representative of Horse and Hound. He tells her she's their favorite actress...after Black Beauty, of course.
The idea that vampires burn in the sun is actually a relatively new one. It first appeared in 1922, with the film NOSFERATU. Count Dracula, Varney the Vampire, Lord Ruthven and other early vampires could all walk in the sun with no detrimental effect.
