I found an old interview from 1994 conducted by the Vermont Business
Magazine with Christopher Lloyd's older brother Sam. For those who
don't know, Sam Lloyd is a very prominent person in Vermont
politics, theater, and philanthropy. Anyway, for any of you who
listened to the commentary on the Special Edition DVD of "One Flew
Over the Cuckoo's Nest", you know that Michael Douglas became
familiar with Christopher through his broher Sam, who was acting on
Broadway att he time. Anyway, here's the snippet from the interview
that mentions a funny anecdote about Christopher Lloyd:

VBM: Is your family a theater family? Everybody knows of your
brother, Christopher.

LLOYD: No, not really. My father was a great story teller. My mother
had a lovely singing voice, but when she was brought up, in her day
and time and situation, professional performing was not looked upon
favorably, so she was never able to sing professionally. But that's
all.

My sisters and brothers were extraordinarily gifted. I have
paintings by my three sisters. My sister Ruth is a wonderful
musician, plays classical piano magnificently, and also has written
a book on psycho-immunology. I can't even pronounce it, and I can't
read her book, it's so complicated. She has just gotten her Ph.D.--
she's Dr. Ruth Lloyd. My youngest sister, Adele, paints very
successfully out in the Seattle Northwest. My oldest brother,
Donald, is one of the great jazz pianists that I've ever heard, who
can play jazz without reading a note, or right off the top of his
head.

And then, of course, there's Christopher, who has an extraordinary
talent. So where it all came from, who knows. I don't.

VBM: Do you see much of Christopher?

LLOYD: Yes, two or three times a year. We were hoping he'd be able
to make it back to the Playhouse again this summer, but a conflict
came up. A film job, which, of course, he couldn't turn down. But
he's committed to coming back again, and he loves it here. I brought
him here for his first professional appearance.

VBM: Is that right?

LLOYD: Yep. Doing the very same production that I had understudied
on Broadway, "A Shot in the Dark."

VBM: Oh, yes,

LLOYD: Which is a fun comedy, a mystery. And I played the part, the
Walter Matthau part, that I had understudied on Broadway. And
Christopher played the William Shatner part of the detective. And I
must say it was a stumbling beginning for the poor kid.

He had never done anything beyond short scenes in acting class. And
here, in a week's time, he had to learn a whole part, a whole role,
a very long role. So it was very lucky that he sat through most of
the performance at his desk with a window right behind him, and the
stage manager lurking right behind that window with a script, to
give him the lines. Well, that was his beginning, and he's gone on
magnificently since then.
