A Joker/Harley movie would be awesome. Don't see the need for a seperate solo film for both of them, that seems a bit much.
I'm not even sure about a straight Harley movie... I think she is a great character but she is going to need some people to help her in a solo-ish movie. possibly the Gotham City Sirens?
I don't think there is any way a Captain Boomerang solo movie would work... but I think he is going to be a great character in SS.
To the general audience, no one knows about SS, let alone who the members include.
I was just reading some stuff and how awesome would this be to see on film?...minus the Joker being dead and all
"After a falling out with the Joker, she goes into a murderous frenzy, directed towards people responsible for the Joker's imprisonment. Captured by
Black Canary, she is forcibly inducted into the
Suicide Squad by
Amanda Waller.
[14] However, when she discovers that the Joker is rumored to be dead, it takes a further toll in her already addled mind, and betraying the Suicide Squad, she puts their safety and secrecy at risk by turning herself into the Gotham Police Department in a plot to gain access to the skinned face of the Joker.
[15] Her plan apparently pays off, and she manages to recover the face, though in a further psychotic episode, Harley captures and ties up Deadshot and places the skinned face of the Joker over Deadshot's face, so that she can carry on a "conversation" with her dead lover.
