While we're still months away from the fourth season premiere of Mad Men, we're just days away from production getting underway on the show's opening episode.

Shooting is scheduled to begin on April 12.

As for what fans can expect on the new season, creator Matthew Weiner has been tight-lipped as always. But Entertainment Weekly has broken the news that three recurring characters will be added to the cast.

They'll include:

• A handsome/creative male.
• A voluptuous, curvy, brunette (possible rival for Joan?).
• A nice guy with a lack of a personality.

Are you excited for season four of Mad Men?
