Let's hear some of those preliminary ones you have. I can give you some feedback.

I'll have to give it some thought.
I have considered alternative Batman casts over the various decades from the 30s onwards before but I might to rethink them.
I'd love to get your thoughts on casting a live-action B:MOTP for the 70s and 80s but even more interesting would be a hypothetical cast for the entire Batman: The Animated Series cast encompassing all the Rogues' Gallery and key supporting characters.
Oh, you English are
so
superior, aren't you?

It's decent casting, for sure. How about we up the ante? How about a 70's or 80's (or any other decade) Batman Mask of the Phantasm movie?

Cool. So my final cast is the following:
Bruce Wayne/Batman

• Jon Hamm
  Andrea Beaumont/The Phantasm
• Rachel McAdams
  The Joker
• Alan Cumming
  Alfred Pennyworth
• Clive Merrison
  Commissioner James Gordon
• Bryan Cranston
  Carl Beaumont
• Richard Gere
  Arthur Reeves
• Justin Theroux
  Oh, you English are
  so
  superior, aren't you?

For the Joker, I would go with Alan Cumming. I also Richard Gere as an alternate Carl Beaumont. Rachel McAdams would be a great Andrea.

Good choices, man. What about your modern cast?
Tough, but I'll give it a go.
Bruce Wayne/Batman

Jon Hamm
(although I think Ben Affleck is a great choice for the character - I just wanted to go with an alternative to the official choice)
Andrea Beaumont/The Phantasm

Rachel McAdams
(and after 'Gone Girl' maybe Rosamund Pike)
The Joker

• I can't think of any specific choice so I'll offer the following:
  Tim Roth
  /
  Crispin Glover
  /
  Alan Cumming
  /
  Adrian Brody
• do you think any of the are good choices, and who would you pick out of them?
  Alfred Pennyworth

Clive Merrison
Commissioner James Gordon

Bryan Cranston
Carl Beaumont

Tom Selleck
(a good choice, but like I say, I'd prefer him to play Dr. Thomas Wayne, so alternatively, Bruce Greenwood, Treat Williams or Richard Gere)
Arthur Reeves

Justin Theroux

I really love these choices longi-2. The only one I'm not so sure about is Chastain for Andrea Beaumont, mainly because Chastain is my favourite actress at the moment but I think she tends to excel a playing more down-to-earth characters with a sensible head on their shoulders than Beaumont who is ultimately revealed to be a mentally unstable rich girl. I'd prefer to see Chastain play Batgirl/The Oracle or even Poison Ivy (who starts off as a shy nerd before becoming as complete nutter).
Okay, this is my hypothetical cast for 1993:
Bruce Wayne/Batman

• Alec Baldwin (Gibson would be my second choice, although he's not very tall and in retrospect it's probably a good thing he wasn't cast as Batman in view of the controversy he's since attracted)
  Andrea Beaumont/The Phantasm
• Jeanne Tripplehorn (Robin Wright as a secondary choice)
  The Joker
• Willem Dafoe
  Alfred Pennyworth
• John Hillerman
  Commissioner James Gordon
• Tom Skerritt
  Carl Beaumont
• Cliff Robertson (Tom Selleck is a great choice for a present day version of the film, although I've always thought he'd be a perfect choice for
  Thomas Wayne
  in flashbacks)
  Arthur Reeves
• John Cusack
  Oh, you English are
  so
  superior, aren't you?

1993
Bruce Wayne/ Batman: Mel Gibson or Alec Baldwin (I'm a huge Michael Keaton fan, but his version of Batman wouldn't really work in this movie)
Andrea Beaumont/ The Phantasm: Rene Russo or Catherine Zeta-Jones
Arthur Reeves: Kevin Spacey
Carl Beaumont: Robert Redford
The Joker: Willem Dafoe
Alfred: Anthony Hopkins
Commissioner James Gordon: William H. Macy
Today
Bruce Wayne/ Batman: Ben Affleck or Hugh Jackman (assuming he never played Wolverine)
Andrea Beaumont/ The Phantasm: Jessica Chastain or Jennifer Garner
Arthur Reeves: Liev Schreiber
Carl Beaumont: Tom Selleck
The Joker: Tom Hiddleston (assuming he never played Loki) or Hugo Weaving
Alfred: Michael Caine (Sorry, just can't see anyone else in the role)
Commissioner James Gordon: Bryan Cranston
