I love the two of them! This sounds great! HBO is really putting some great movies out there, lately.

From Deadline.com:

It took James Gandolfini 6 years to get the story of Ernest Hemingway and Martha Gellhorn to the screen.

Now HBO has just given the green light to Hemingway & Gellhorn, an original movie produced by Gandolfini, who first was attached to star in the project in 2004 when it was envisioned as a feature.

He then brought Hemingway to HBO through his Attaboy production banner, which has been based at the pay cable network since 2006.

It was worth the wait now that it stars Clive Owen and Nicole Kidman as one of American literature’s most famous couples.
