Jennifer Aniston tells ET's Thea Andrews she loved her role reversal with "Late Night" host Jimmy Fallon "a little too much" -- but the actress plans to keep her day job, starting with promoting her new film 'Management' alongside her costar Steve Zahn.

Aniston says she would consider filling in for Fallon somewhere down the line, but right now she's enjoying movies! "We had so much fun it was shocking that we were at work," the actress said of working on 'Management.'

In the film, Aniston plays a traveling saleswoman who sells cheap art to small companies and motels. During one of her stops, she has a fling with an aimless assistant motel manager played by Zahn, who subsequently pursues her around the United States. The film is set to hit theaters May 29.
