New Interview w/ Rob Lowe on Why He Left
Rob Lowe tells GQ:
"I left Brothers & Sisters when they ran out of storytelling runway. I mean, there are so many family dinners you can do. I eventually had to go to them and say, 'Look, I don't do spatula work. I don't do scenes with oven mitts. If you're looking for that, you've got the wrong guy. I'm not doing scenes about casseroles. It's not happening.'"
In 2010, when his exit was announced, a source had told E! News that Lowe was departing "Brothers & Sisters" because he felt he was being underutilized in the ABC family series and had asked to leave the show, adding that the move was amicable.
