Mother Teresa once said, "peace begins with a smile". Then again, not all smiles look pleasant or even peaceful. Some can give you the creeps and will not let you sleep in peace. Today, on World Smile Day, we have compiled 11 of the creepiest smiles from the movies. World Smile Day is celebrated on the first Friday of October every year. It was initiated by artist Harvey Ball, who is known to have created the 'smiley face' in 1963. The idea is to "do an act of kindness and help one person smile." Here's our twist, which in the words of The Joker, might put a smile on that face.

Jack Nicholson in The Shining (1980)
"Here's… JOHNNY!"


Nicholas Cage in Vampire's Kiss (1988)
This, of course, became the very popular 'You Don't Say meme'.


Saswat Chatterjee in Kahaani (2012)
Proper 'looks harmless but very creepy' guy. And we know how things turned out.


Anthony Perkins in Psycho (1960)
That smile in the end.


Harvey Spencer Stephens in The Omen (1976) 
Talking of "that smile in the end", let's take a moment and think of this one.

Christian Bale in American Psycho (2000)
Throughout the film.


Willem Dafoe in any film (creepy since 1955)
Born to play the villain.


Christoph Waltz in Inglorious Basterds (2009)
Twisted intentions behind that perpetual smile.


The Jokers
How can we talk about creepy smiles without including The Jokers? Three of the best so far – Jack Ncholson, Jared Leto and Heath Ledger.


Nawazuddin Siddiqui in Kick (2014)
The perfectly sinister villain.


Jim Parsons in The Big Bang Theory (2007 – present)
Well, at least he tried.
