NEW YORK (AP) – No need for time travel for Michael J. Fox. The actor says he's happy with his life just the way it is.

In fact, Fox says if he could jump in a DeLorean time machine – like his "Back to the Future" character Marty McFly – and share any advice, he would say "keep doing what you're doing." Fox says the role brought him to where he is now and he "wouldn't want to be anywhere else."

Fox marked the 25th anniversary of "Back to the Future" at an event Monday in New York City.

He says the 1985 film gave him worldwide notoriety and that he could "walk down the street in Bangkok" and hear "Marty McFly!"

Fox was diagnosed with Parkinson's disease in 1991. He no longer acts regularly, but will appear on an upcoming episode of "The Good Wife" on CBS.
