Remake

Negative. It's already a stage play made into a movie.

L.A. Theatre Works recorded the original play using:

Joe Mantegna as Ricky Roma
Gordon Clapp as David Moss
Kyle Colerider-Krugh as Detective Baylen
Richard Dreyfuss as Shelly Levine
John Getz as James Lingk
Richard Schiff as George Aaronow
Josh Stamberg as John Williamson

I bought it. It was surprisingly poor. Dreyfuss in particular sounded like he was phoning it in.

There was a brief Broadway revival in 2005 with Alan Alda (QED, "M*A*S*H") as Shelly Levene, Jeffrey Tambor (Sly Fox, "Arrested Development") as George Aaronow, Liev Schreiber (Henry V, "Scream") as Richard Roma, Gordon Clapp ("NYPD Blue," "Moonlight Mile") as Dave Moss, Tom Wopat (Annie Get Your Gun, "The Dukes of Hazzard") as James Lingk, Frederick Weller (Take Me Out, "The Shape of Things") as John Williamson and Jordan Lage (The Best Man, "The Spanish Prisoner") as the detective Baylen.

That one sounded pretty intense, especially with Alda and Schreiber -- easy for me to imagine them in the roles yet playing them VERY differently from Lemmon and Pacino. I've never found any clips of that one, sadly

Lastly, in 2012, there was a short experimental run that I think closed quickly to tepid reviews. It starred Bobby Cannavale as Roma, along with David Harbour and Richard Schiff (I'd guess as Moss and Aranow), and the ULTIMATE recasting: Al Pacino as Levene.

That would've been HILARIOUS, or it should've been. He's played insecure before ("Sea of Love"). But again the critics were harsh, claiming Pacino was essentially still experimenting with the role.

EDIT:

Just found this:

So Harbour was Williamson, McGinley was Moss, and Pacino was, indeed, sadly slacking off (rather like Dreyfuss ... maybe the role's too much for a typical "alpha male" to handle). Everyone else looked great, though.

It's hard to picture a newer version of GGR with new cast members. If I was king I'd get all the surviving cast members to do a 1 year run on Broadway but replacing Jack Lemmon is a HUGE task. He had all the pathos required for the role, Hanks can't pull it off. I know the recent attempts at revival have been lackluster gotta get the casting right before pressing further.

A remake would be full of horrible overacting and mugging for the camera.

Vin Diesel could not sell the role.

A reboot would have to be an all vertically-challenged lesbian Pygmy cast.
