"Of course I was in favour of him doing the part. But the kids don't really get it. They don't really know those films. They'll understand soon enough but right now that's a bit of a fog for them.
Asked whether she wanted Affleck to take on the time-consuming role of Batman in the upcoming 'Man of Steel' sequel, she said, "Thankfully we don't look at the year ahead and go, 'OK I'll work these two months, you stay at home', It's more like, 'This has come up.' So before we panic and say we can't do it, let's sit down together and see if we can make it happen. Maybe Brad (Pitt) and Angelina (Jolie) can plan their lives like that, but it doesn't work like that for us."
"After I did 'Dallas Buyers Club' I took another break because I wanted to be around for Ben when he was travelling with 'Argo'. I felt like I needed to be there with him, which wasn't a decision I took lightly. But Ben had been home while I was working and, really, we just try and make it work," Garner said.
