McMillan, now 45, is a TV writer in Los Angeles. [Her credits include] “United States of Tara” , the fourth season of “Mad Men” and her current job on Jerry Bruckheimer’s upcoming NBC series, “Chase.” What makes this roster even more impressive is that she didn’t start what she calls her “dream job” until just a few years ago, when she scored her first show, NBC’s now-canceled “Journeyman.” McMillan recalls one day while working on the drama about a time-traveling reporter, the show’s writers went around the table and talked about what their dads did for a living. “Out of the nine writers, six of them had dads who were doctors,” says McMillan on the phone from her home in Los Angeles. “And I said, ‘My dad’s in federal prison.’ That’s why it took me 20 years to get here. I ran a marathon before I got to that table.” That marathon is documented in her new Advertisement Quantcast memoir, “I Love You and I’m Leaving You Anyway”.
