Q. How has success changed youngster Macaulay Culkin, the "Home Alone" star?
A. He may be a $200 million boy, but he still talks like a 10-year-old. "We ride and bike and do stuff like that," he explains. But his agent is somewhat more expansive. "If environmental groups knew how much paper was being spent on" Culkin, says Paul Feldsher of International Creative Management, reflecting on the inundation of scripts, "I think we could save a rain forest somewhere." Next up for Culkin is Columbia's "My Girl," for which he will take away a reported $1 million.Q. Give some information on Mark Hamill of the "Star Wars" trilogy.

Q. I'm a great admirer of Max von Sydow. Tell me about him - age, nationality. How many films has he done? - R.B., Bridgeport, Pa.

Q. I've checked every video store and none has John Astin's delightful comedy "Evil Roy Slade." Where can I get the tape? - H.B., Glendale, Calif.
A. The 1971 western spoof with Astin, Edie Adams, Milton Berle and (in a small role) John Ritter isn't available on videocassette.

Q. Help! I say Andy on "One Life to Live" and Brenda on "Beverly Hills 90210" are the same person. My friend disagrees. We've got 10 bucks riding on who's right. - L., Atlanta.
A. Pay up. Bronwen Booth plays Andy Harrison on "OLTL." She's done other soaps but only as a day player - no regular roles. Shannen Doherty is Brenda in "Hills." You may remember her from NBC's "Our House." Doing two shows would be tough if both were produced in the same town, but "OLTL" is based in New York and "Hills" is in California. Coast-to-coast commuting is usually reserved for important stars.
Q. What does Joni Mitchell, a survivor of folk and rock, think about changes in music?
A. "I've always thought about the spirits of music, you know," says Mitchell, whose new album is "Night Ride Home." "Like rock 'n' roll: People keep writing songs about how rock 'n' roll will never die. Well, rock 'n' roll died a long time ago. It never even made it into the '60s. The roll went out of it. What died was the push beat, the remnant from swing and boogie-woogie. And when it died, what was left was just rock . . . A certain joy went out of rock 'n' roll, and what was left was a militancy - which I guess makes sense because of the times."
Q. How is actress Ally Sheedy bearing up under those mean-spirited reviews of her new book of poetry?
A. Sheedy, 28, makes no secret that her book, "Yesterday I Saw the Sun," helped heal some of the deep wounds she has suffered as a child star.

Her early success, starting with the American Ballet Theater at age 8 and publication of a children's book at 12, was coupled with bulimia, a teenage abortion, drug addiction and attempted suicide. After rehabilitation at the famous Hazelden Clinic, Sheedy wrote the poems "because I needed to write them. . . . It's about recovery."

"Living agrees with me."

A. Frances Fisher played Lucy. She is a soap opera veteran, as Donna Saxon in "The Edge of Night," but most of her credits are in off-Broadway plays and minor TV and movie roles.

Q. Settle this between friends: My friend insists that Garry Marshall is Penny Marshall's father. I say he's her brother and hired her for "Laverne & Shirley." - L.V., Burns, Ore.
A. Garry is Penny's brother, and he did give her her start, in a bit role in the pilot for his series "My Friend Tony."
