GOOD MORNING: Merry Christmas: a mellow Marlon Brando predicts his recently wound “Island of Dr. Moreau” “could make $500 million.” It would please him no end since he says he’s got 15% of the gross. “Island” was momentarily shipwrecked when, after five-days’ shooting, director Richard Stanley was replaced and John Frankenheimer took over (and reshot those five days). Brando tells me Frankenheimer “is one of the best directors I ever worked with — he gives an actor wonderful latitude.” Frankenheimer returns the compliment: Brando “is the best actor of this generation. I always wanted to work with him. He’s the reason I am in this business — after having seen him in ‘Streetcar Named Desire’ — when I was 19!” In “Moreau,” Frankenheimer got Brando to do some very interesting things — like singing again (remember “Guys and Dolls”?). This time the song’s “Froggie Goes A-Courtin’ ” He also plays the piano, Chopin’s “Polonaise,” duetting with actor Nelson De La Rosa, who, Marlon says, is 18 inches tall and sits atop the piano while Brando plunks. Marlon also notes of “Moreau” makeup by Stan Winston, “I was stunned!” Winston creations include a pig-lady, bear-man, etc. “I laughed so many times I broke up the scenes!” Brando said. He further revealed he loved the ruptured “Divine Rapture”– he hopes the movie can be resuscitated and return to Ireland. “I got one quarter of my salary ,” he said, “but the others (John Hurt, Debra Winger, Johnny Depp and director Thom Eberhardt) went home unpaid.” Brando continues to get many film offers, including the Miami-set “Romeo and Juliet” for 20th starring Leonardo di Caprio and Claire Danes — but he nixed the role of Friar Laurence. Next for the environmentally involved Brando is a trip to Germany to investigate a power-saving photo cell — he’s considering converting his house to the 48-volt power source.HAPPY HOLIDAY NEWS for Lynn Redgrave, who successfully emerged from Chapter 11 bankruptcy this week, thus ending 15 years of litigation, first against MCA/U , then against her Finley Kumble lawyers — the latter themselves declared bankruptcy in 1987.
