​Here's the First Trailer for Joaquin Phoenix's 'Joker' Movie
After teasing us with a photo transformation, Joaquin Phoenix is making his official debut as the Joker in a trailer for the Todd Phillips-directed Joker.
 
The trailer shows us the titular character's journey from a lonely clown to the delightfully insane villain. As you will witness, the first clip is totally unsettling, blurring the lines between horror, tragedy, comedy and action.
 
Joker hits theatres on October 4. Watch the first trailer below.
