Suicide Squad Movie....This Won't End Well

DC Comics has decided to make a film adaptation of the Suicide Squad.  An obscure government funded group of convicts implanted with explosives into their skulls are sent on missions to make the world a better place.....  FUN TIMES!?... Right?..... Right???  Lets take a look at how this can all go oh so wrong.

Writers: Ross Andru; Robert Kanigher; John Ostrander and Justin Marks.  So Three of the comic's writers and one screenplay writer.  The Screenplay writer Justin Marks is known for his work on Street Fighter The Legend of Chun-Li.....

Director: David Ayer I have some hope for.  He has a good few movies that did fairly well under his belt in both directing and writing and producing.  

The Cast this is where a movie can be made or broken if not done right.

IMDB has some of the cast listed as rumored and IGN has the cast as confirmed. Hmmmm  Lets analyze

Jared Leto: Joker (IMDB Not listed at all not even rumored; IGN is saying Confirmed)
Tom Hardy: Rick Flag (According to IGN) Simply Rumored and not given a character by IMDB
Jai Courtney: Boomerang (According to IGN) Deadshot (Rumored According to IMDB)
Will Smith: Deadshot (According to IGN) and listed as Simply Rumored and without a character by IMDB
Margot Robbie: Harley Quinn (According to IGN) Confirmed on IMDB
Cara Delevingne: Enchantress (According to IGN) Not listed on IMDB
Jesse Eisenberg: Lex Luther (Listed as Rumored in both IMDB and IGN)

Why the Joker?  The Joker has NEVER been a member of Suicide Squad in ANY of it's incarnations so why throw The Clown Prince of Crime into this rag tag group?  For the Harley/Joker love story?  It doesn't work with the premise of the story.  Even by the groups leader Amanda Waller's standards finds Joker far to unstable.  There is no need to throw Joker into the mix.  For that matter there is no need to throw Lex Luther into the mix either.  Unless they are going to go a new route and have The Joker and Lex combine forces to create The Suicide Squad... I can see that working but the partnership would be far to strained to last long.

What would the story even be like.  As Amanda Waller isn't even listed as a character who is going to be the Nick Fury of this unstable group of bomb strapped expendables? 

Why Tom Hardy? He has been established as Bane and a damn good Bane to boot.  Why have him portray Rick Flag? By this I am guessing it is going to be the grandson as the original Rick Flag was in the WWII incarnation of Suicide Squad.

Needless to say I am not all that hopeful for this movie.  However I will continue to keep my eye on the development of this movie.

Update:  nerdist.com has confirmed the cast of Suicide Squad still having Lex Luther as just being rumored.  Adding to the rumored cast list.  Amanda Waller has 3 possible actresses.  Viola Davis, Octavia Spencer, or even possibly Oprah Winfrey
