LOS ANGELES (AP) - It was a hit more than 20 years ago. So Fox 2000 is looking to light a new fire under an old movie. The studio will re-ignite the comedy "Mrs. Doubtfire," which starred Robin Williams. No deals are in place yet, but a Fox spokeswoman says Williams and Chris Columbus are in talks to be aboard, with Williams re-doing the role of a man who dresses up as a Scottish nanny to spend time with his kids - and Columbus directing. The original film made more than $400 million worldwide. Among the movie's funniest scenes is when Williams fake breasts catch fire - and he puts them out with a pair of pot lids.
