Many famous actors and actresses starred in some music videos - Halle Berry starred in Limp Bizkit's version of "Behind Blue Eyes"; Angelina Jolie was great in "Did My Time" by Korn; Macaulay Culkin, Chris Tucker, Danny Glover and many others appeared in Michael Jackson's clips; and you can see Robert Downey Jr. in "I Want Love" by Elton John.
But I was so surprised when I noticed that the Vampire from one music video of Pet Shop Boys looks like Ian McKellen. And it turns out to be him! I like his image of an old and noble vampire, who knows how to hypnotize a young pretty girl.
