Ben Affleck has tackled a lot of great roles, but he's most eager for his next important task: playing house.

Having just wrapped his latest flick -- with costars Javier Bardem and Rachel McAdams -- in Oklahoma, the actor, 38, is excited to spend time at home with wife Jennifer Garner, 38, and their daughters Violet, 5, and Seraphina, 23 months.

"My wife's going to a movie and then it's going to be just pure Mr. Mom time!" he told at the NYC premiere of his new drama, The Company Men, Wednesday.

Also on his to-do list: hitting the mall. The star recently admitting on The Ellen DeGeneres Show that he often picks up Garner's Christmas presents "at, like, CVS on the 24th."

"It sounded bad, I know!" he told Us. "When I watched it I was like, 'I don't come off very well here.' But I have that experience quite a bit."

Continued Affleck, "Basically, my wife is very in-depth with all this stuff, really sharp, very thoughtful, very thorough. And so for me, I get kind of panicked, I put things off and I just don't know what to get so just buying her a present -- I put more work into that than she does into buying fifteen!"

But her organized shopping habits aren't the only thing the star digs about his gal. When asked his favorite thing about her, he told Us, "What's not to love?"
