Playing Thompson's husband, Harry, in "Love Actually" Rickman was arguably considered the villain of the movie after his head was turned by his secretary, Mia.

The actor continued to play the role of Severus Snape in all of the Harry Potter movies, as well as directing and starring in the 2014 film "A Little Chaos." Rickman passed away in January 2016 from pancreatic cancer.
