Ben's Gone Girl and Jennifer's Alexander and the Terrible Horrible No Good Very Bad Day kept the parents away from their three children for a bit, and Ben explained how he copes with those months that require him to be away at work.

"It's hard because when you have children you balance your work and your family life," said Ben. "I'm fortunate. I have a lot of means at my disposal where I'm able to do that more fluidly, but particularly for women it's hard. It's a hard thing to go: 'If I'm with my kids, I feel like I should be working. If I'm working, I feel like I should be with my kids.' They can't win."

In the movie, based on the novel by Gillian Flynn, Ben plays a man who becomes a suspect in his wife's disappearance.

Jennifer's film has a much lighter tone. The movie, based on the children's book, follows the Cooper family through the worst 24 hours ever.

Speaking of trying days, Jennifer probably had a few in dealing with the kids, who Ben revealed were all sick. In his interview with ET, Ben relayed a message to his wife, saying, "I want to ask her how the kids are doing and how she's doing. I hope she's holding up alright, because our kids are all sick."

"Everybody is on the mend," Jennifer answered during our interview the following day. "You can let him know."

Jennifer's Alexander co-star Steve Carrell joked that it was "sweet" to see the couple corresponding through the press.

"That's a special and very personal way to do it," Steve quipped.
