THE ART OF THE SCENE STEAL
The Donald Trump-type character in director John Derek's film Ghosts Can't Do It, due this fall, is played by—a drumroll please—Donald Trump. He portrays Mr. Spectacular, a leveraged-buyout king whom Bo Derek battles to save her husband's (Anthony Quinn) business after she's widowed. Says Trump: "After I did it, I found out the name they had given me. Of course, being the modest person that I am, it bothers me quite a bit." Trump says he agreed to the cameo, which was filmed in his office, because he's a pal of the Dereks and it was fun looking at Bo. "The beauty of playing myself is that it goes very quickly since nobody can tell me I'm doing it wrong," says Trump, who played himself once before in the TV miniseries I'll Take Manhattan.

GRATUITOUS BEHAVIOR
Ah, the high cost of fame. Nadine's, a small New York bistro, gets many familiar customers because it's near the HB Studio, site of well-attended acting classes. Nadine's staff recently took a straw poll: The waitresses voted Robin Williams, left, their favorite customer, while Bruce Springsteen, center, was tops with the waiters. Both had acted like nice guys rather than big shots (Bruce even bought beers for the next table) and were generous tippers. But manager Jimmy O'Hagen says the best tipper is tiny playwright-actor Wallace (Scenes from the Class Struggle in Beverly Hills) Shawn, right. Wally usually tips 110 percent of his check. He's followed by Larry Hag-man, who left 100 percent. Others, including Caroline Kennedy, Daryl Hannah, Melissa Gilbert, Matthew Broderick and Patrick Swayze, leave 20 to 30 percent. O'Hagen won't say who tips the least.

MORE GRATUITOUS BEHAVIOR
A new trend in Hollywood should please producers: pro bono acting. Wynona (Heathers) Ryder and Matthew (Married to the Mob) Modine wanted no fee from Virgin Records for doing the video for the late Roy Orbison's "A Love So Beautiful." "They wanted to do it because they are fans of director Matt Mahurin and Orbison," says producer Sharon Oreck, adding that they were paid nominal fees. Also shunning filthy lucre is the $1.5 million-a-day-man, Marlon (Superman) Brando. He waived his usual fat check for the forthcoming film A Dry White Season because he believed so strongly in its antiapartheid message. But, MGM/UA producer Paula Weinstein says, he did get union scale.
