This film is a bad joke.  Drop it at the first sign of trouble.
 
FUN FACT:  The film's subtitle "Folie a Deux" means "Madness of Two" in French. This initially led to speculation about Harley Quinn's appearance in the film, which was shortly thereafter confirmed. The name Folie a Deux comes from the 19th century French psychiatrists Charles Lasègue and Jules Falret. The term was coined to refer to two or more people that share the same madness or delusion. It is also known as Lasègue-Falret syndrome.
