Back to the Future's Christopher Lloyd would love to reprise Doc Brown

Pass the lab coat, wacky printed shirts and hair teaser: Backto the Futurestar Christopher Lloyd is eager to play Doc Brown again.

"If they want to do some more, have Doc appear in a film, film a cameo, I'm happy to do it," the 76-year-old actor, who played the passionate, frizzy-haired scientist in the Back to the Futurefilms, said in a telephone interview.

"I love the character and I love doing it."

The beloved franchise celebrates a milestone on Wednesday: Oct. 21, 2015 was the exact day and year that Marty McFly, played by Canadian Michael J. Fox, travels into the future in the second part of the series.

Jumpstart to career, 1st onscreen kiss

Lloyd said the first film, which hit its 30th anniversary in July, lit a flame under his career as hot as the one that burns behind Doc's DeLorean car when it blasts through time.

"The film 'Back to the future' certainly did a lot to put me where I am today and I did not foresee that," he said. "I just was hoping the film would open successfully, the first one, but it's gone way beyond what I think most of us have imagined.

"It doesn't quit."

The franchise even led to a personal milestone: His first onscreen kiss.It was with Mary Steenburgen, in Back to the Future Part III.

"Not only was it my first, it was my only," said Lloyd. "I can't think of a film where there's been a romantic kiss of any sort, so I treasure that."

We've had quite a ride.- Christopher Lloyd

Robert Zemeckis directed the three Back to the Futurefilms and also co-wrote them with Bob Gale.

Lloyd said an early draft for the first film had Doc Brown going to an atomic test site in New Mexico with Marty in the DeLorean, to get energy to travel into the future.But they changed it.

"I'm glad they did," said Lloyd. "I think it would've put a kind of darkness to the film I don't think they wanted."

Lloyd said he still has one of the shirts Doc wore in Back to the Future Part II.

"It's more or less yellow with little steam engines going around on it. I haven't been wearing it. It's just hanging in the closet all these years."

And he still keeps in touch with Fox.

"We've had a chemistry that just is innate," said Lloyd. "We didn't have to figure out how to bring our chemistry up to the level that was necessary for the film. It's just present automatically and so it's been great.

"We've had quite a ride."
