ET's Nischelle Turner spoke with Affleck at the premiere of his new crime thriller, Triple Frontier, in New York City on Sunday, and the actor opened up about how his Batman-loving little boy dealt with the fact that his famous father had hung up his cape and cowl.
"He took the news okay. He kind of understands that there's time for everything," Affleck said.
The actor was originally set to direct a standalone Batman film in the future, which he would also star in, but he admitted recently that he wasn't able to make it work, from a creative standpoint.
"[Samuel] is not quite old enough to understand that I was gonna direct [a Batman movie], but I couldn't figure out how to do it," the 46-year-old Oscar winner shared, adding, "I didn't love it enough."
In terms of how he explained the situation to his little boy, the star said he broke it down in terms his young son would easily grasp.
"I just kinda stuck with like, you know, 'It was my turn and now it somebody else's turn.' Because he understands turn taking," Affleck quipped.
Affleck -- who played the Caped Crusader in 2016’s Batman v Superman: Dawn of Justice and 2017’s Justice League, and had a brief, batsuited cameo as the Dark Knight in 2016's Suicide Squad -- confirmed that he wouldn't be returning as the iconic hero while sitting down on Jimmy Kimmel Live! last month.
"I tried to direct a version of it and worked with a really good screenwriter, but just couldn’t come up with a version, I couldn’t crack it,” Affleck said. "So I thought it was time to let someone else take a shot at it. They got some really good people so I’m excited."
