After calling estranged wife Jennifer Garner the "world's greatest mom"
on Monday, Ben Affleck shared with ET that he has plans for a fun family vacation over the holidays.
"I can tell you that we're going to do skiing in Montana with our family and Matt Damon's family and my brother's family," Affleck revealed at a special New York City screening of Live by Night. "It should be a lot of fun."
These plans come amid rumors that Affleck and Garner may be reconciling following their split last year after 10 years of marriage. Last month, the former couple was spotted attending church together with their three children -- Violet, 11, Seraphina, 7, and Samuel, 4 -- in tow.
Affleck oozes gangster swagger in the upcoming mob movie, based on the Dennis Lehane novel of the same name. The 1920s drama follows the saga of Joe Coughlin (Affleck), a cop's son who turns to a life of crime and finds himself rising to power in Boston. After a stint in jail, he's released to start over in Florida, and it’s in the Sunshine State where the once straight-edged U.S. soldier finds himself caught between two rival gangs and two femme fatales, played by Zoe Saldana and Sienna Miller.
"It's kind of a classic, throwback gangster movie," Affleck told ET. "It kind of harkens back to the classic era of cinema, I hope. It's meant to be a love letter to the great movies of old, where you had great sweep and scope and extras and design and big, sexy, punchy themes."
While he had to wear many hats on this project -- he was an actor, writer, director and producer on the film -- Affleck gave credit to his team who made things easier for him. "I had Leonardo DiCaprio to rely on as a producer," the Oscar winner said. "I know him pretty well. He's a very good guy. He's a friend of mine and a really smart guy and somebody who really understands a lot about movies."
In addition to his two Oscar wins, Affleck also has two Golden Globes on his mantelpiece, and next year, there might be another Golden Globe winner in the family, as his younger brother, Casey, is nominated for his performance in Manchester by the Sea.
"I'm absolutely thrilled," Affleck said about his brother's nomination. "I think he deserves it. He's deserved it for a long time. I casted him in my first movie I ever did, Good Will Hunting. What a talented actor he was, and I'm really glad he got the opportunity to showcase that."
Live by Night opens in limited release Christmas Day.
