As it is past midnight in the U.K., today - March 10, 2010 - marks Remus Lupin's birthday! Had the lycanthrope Defence Against the Dark Arts teacher, father of Teddy Lupin and husband of Nymphadora Tonks, and Order of the Phoenix member lived to see past the final battle, he would have turned 51 years old today.

Remus Lupin is played by actor David Thewlis in the Harry Potter series.

Happy Birthday, Remus!
