Well, he might not need your help, but he’s the director of the long-awaited “A-Team” movie, but doesn’t yet have a cast
So, who should play the four main characters? The story mentioned Woody Harrelson and Ice Cube as Murdoch and B.A, respectively.
Here’s my picks:
Murdoch: David Arquette
Face: Ethan Hawke
BA: Ice Cube
Hannibal: Harey Keitel
Murdoch: Sean William Scott
Face: Ben Affleck
BA: Dwayne Johnson
Hannibal: George Clooney
Murdoch: Adam Baldwin
Face: Ben Affleck
BA: Ice Cube
Hannibal: Nathan Fillion
Murdoch: Alan Cumming
Face: Terrence Howard
BA: Michael Clark Duncan
Hannibal: Neal McDonough
I like Alan Cumming for Murdoch, but if you’re gonna do that you need Jonathan Pryce (who *can * do an American accent, btw) as Hannabal
Face: Katee Sackhoff
Hannibal: Kermit
Faceman: Hogthrob
Murdock: Gonzo
B.A.: Sweetums
Amy: Piggy
if you’re going there, then
Hannabal: Bugs Bunny
Howling Mad Murdock: Daffy Duck
Face: Pepe LePew
B.A. [del]Elmer Fudd[/del] Sylvester
The Whedon Team!
Face: Nathan Fillion
Murdock: Adam Baldwin
Hannibal: Anthony Stuart Head
BA: Summer Glau ('cause we need a waif-girl in the toughy guy role, c’mon, when they have to drug her to get her on the plane or she kicks everybody’s ass? Comedy gold!)
Amy: Jewel Staite
better Face from the Whedon team would be James Marsters
I would have nominated Boreanaz as the Face. Oh, well.
B.A. - Hector the Bulldog
I defer. 
Hannibal: Peter Griffin
Murdock: Joe Swansen
BA: Cleveland Brown
Face: Glen Quagmire (“Giggity!”)
Seriously, I have two set of answers. A price-is-no-option and a budget cast. Mix and match the two as needed.
Hannibal: Bruce Willis (it would become less an ensemble at this point!)
Murdock: Matthew McConnaghy (could play Face, but not suave enough)
BA: Ving Rhames (the ONLY choice!)
Face: Christain Bale (GQ good looks)
Hannibal: Kurt Russell (gets the second look at any script Willis passes on)
Murdock: Josh Lucas (*always * a low-cost McConnaghy replacement!)
BA: Ice Cube (likely not much cheaper than Rhames, if at all)
Face: Harry Connick, Jr. (not a bad actor)
a very *good * actor, but not nearly pretty enough for Face.
I swear, I came up with my cast before opening the thread, and matched Chimera on two out of four.
Murdoch: Brendan Fraser
Face: Cuba Gooding Jr.
Hannibal = George Clooney
Face = Rob Lowe
BA = Ving Rhames
Murdoch = Jim Carrey
and Christopher Walken as Col. Decker 
Hannibal: Arthur
Face: Andy
Murdock: Johnny
B.A.: Venus
Amy: Bailey 
Frankie Santana: Wilmer Valderama
well heck:
Hannibal: Col Potter
Face: BJ
Murdock: Hawkeye
B.A.: Charles
Amy: Hot Lips
