Before she realized it, Pfeiffer said, "time went by;" her last film, The Family, came out in 2013. "It was actually one of my children who said to me one day, 'Mom, are you ever going to go back to work?'—which kind of hurt my feelings. 'What do you mean? Isn't it great I'm home?'" Pfeiffer recalled. "And then when they started applying for colleges, I thought, 'OK, it is time.'"

Now that her kids are grown, Pfeiffer is happy to be back on set.

"It feels really good, because I don't feel that guilt anymore, [that] working moms feel—you can relate. No matter what profession you're in there's that tug. It doesn't even matter if you're not a working mom—if you're out doing something with your friends, you sort of feel this guilt that you should always be with them," she said. "I am relived of that, so in some ways it's more fun."
