The role of "dad" just isn't what it used to be anymore.  The guys are doing much more of the heavy lifting around the house than most of our fathers did.  More dads than ever are now taking care of everything from diaper duty to laundry to even staying home with the kids so we can pursue our careers.

New Jersey filmmaker Dana Glazer knows this well.  He is living the life of an "evolved dad" himself, as a 37-year-old work-at-home father to two young sons.  The birth of his sons and his decision to stay home with them in a 60-40 split with his interior designer wife spurred his mission to uncover how today's fathers define themselves and their responsibilities.  What's changed since we were kids? And how has fatherhood transformed through the ages?

His documentary in progress, "The Evolution of Dad," is about how men see themselves and how society perceives men.  His goal is to debut the film in theaters on Father's Day 2010.

"You're going to have grown men crying. It is going to dredge up issues about their relationships with their fathers..It really brings this stuff up. You don't realize how deep it goes," he says

The feature film probes this emotional subject through the eyes of men who've made a range of decisions to balance work and family, as well as digging into the latest research by sociologists and psychologists studying gender roles.

More than a year into filming, Glazer believes the movie will provide an opportunity to start a dialogue among men about their feelings around what it means to be a father, masculinity, the role of breadwinner and how fathers are dealing with the daily juggling act of personal and professional commitments. 

"My challenge is how do you show someone going through the conflict of
'I love my kids and it kills me to have to go to work and I barely see them in the morning and I am suffering inside because of it, " explains the NYU Film School grad and freelancer for the Sci-Fi channel and HBO. 

He hopes those fathers who spend too much time at work and agonize that they are missing out on their children's lives will be able to take away a message that, "There are creative solutions...if you can accept a paradigm shift in terms of how you balance your work," he told The Well Mom in a recent interview.

It's a topic ripe for discussion among dads...and moms.  Here's a sneak peek at how "The Evolution of Dad" is evolving so far.
