SAN FRANCISCO (KGO) --The historic home where "Mrs. Doubtfire" was filmed is for sale. It's a valuable piece of property that's also a piece of history.
It's on just about every map and tourist guide, the house where Robin Williams starred in "Mrs. Doubtfire." The movie used the real street address, even real San Francisco food prices.
And it also used something else: "He encouraged the producer to hire all his local friends actors, musicians, comedians," said band leader and actor Dick Bright.

Bright played a waiter, a bit part where you don't often improvise.
"Hit your mark, do a good job and get out. And Robin was like no,'Let's have some fun here,'" Bright said.
It was the playful spirit for which he so well-loved. And that's why the trees and pavement outside that house have become a memorial. The owner explained a couple of years ago why he's left it there.
"I'm not about to change anything, and it's all deserved, isn't' it," said the homeowner.
Some have speculated that one reason the house became an unofficial memorial is there is no official memorial to Robin Williams in San Francisco. Some of his oldest friends are trying to change that.

"We want to rename Sharon Meadow Robin Williams Meadow since he spent a lot of time here at Comedy Day," said San Francisco Comedy Day producer Debi Durst.
In fact, he secretly funded the free comedy show for years. Comedy Day's organizers are now taking donations to change signs to say Robin Williams Meadow.
"Because everybody misses him. And Comedy Day just hasn't been the same without him," Durst said.

The four bedrooms, four and a half bath home is listed at $4.5 million. The seller, quite fittingly, is a retiring surgeon who specialized in facial feminization.
The new owners will have to embrace the home's history.
"I don't think it matters who owns it, it's iconic no matter who lives there," Bright said.
