IT'S NO secret that stars of the entertainment industry make more money performing at private functions than they do from concert appearances. The number of concerts that can be arranged in any given year is limited in comparison to the number of wedding and bar mitzvah bookings that any entertainer can make in the space of a week. Sometimes they may have two or three such engagements in one night. Last week Maariv gave readers an inkling of what they would have to pay to invite certain celebrities to their simcha. There is no standard fee that covers all entertainers, and the discrepancies are quite remarkable. Rita gets $30,000, Zvika Pik $15,000, Harel Skaat (even though he hasn't been in the business for all that long) commands $12,000, while the immensely popular Sarit Hadad gets $9,500 and Dana International $8,000. Surprisingly, Margalit Tsanani gets even less - only $6,000 - despite her frequent television exposure. Tsanani, however, is doing quite well as an advertising campaign spokesperson, which at her age, is quite a feather in her cap. Natalie Portman, the diminutive, Jerusalem-born actress, has chosen the highly acclaimed book A Tale of Love and Darkness by prize-winning, best-selling Jerusalem-born author Amos Oz for her directorial debut. Portman has reportedly signed a two-year contract with Participant Productions for her newly formed Handsomecharlie Films production company. ONE OF the pioneers of Israel's television industry and the founder of the Telad production company, Uzi Peled and his wife Ziona, chose Shefayim for the celebration of their joint birthdays. Son Eyal, who is famous for his televised documentaries, was master of ceremonies and told several anecdotes about his parents. When he was a very small boy, he called them by their first names. This bothered his father, who wanted to be called Daddy, but the young Eyal persisted in calling him Uzi. To try to break him out of the habit, Peled Sr. took the youngster and sat him on top of a tall cupboard, telling him he would not bring him down until he said "Daddy". Eventually the young Eyal complied, but soon after he got lost somewhere, and when a kindly policeman asked him what his father's name was, the little boy was too scared to tell him for fear that he'd be put back on top of the cupboard. ANYONE KEEN to own a 24-karat gold and jeweled pendant that was once worn by actress Sharon Stone can bid for it at a public auction at the Port of Tel Aviv today. Proceeds from the sale, which will include works by some of Israel's leading artists such as Menashe Kadishman, will go to WIZO projects for girls at risk. Stone received the pendant in March last year when she came to Israel as a guest of the Peres Peace Center. She donated it to WIZO for the purpose of helping disadvantaged young girls. Stone is extremely interested in helping youth, and in the course of her visit last year made a point of meeting with Palestinian and Israeli children in schools and hospitals. She also celebrated her birthday while in Israel, and at a glittering party in her honor she declined gifts, asking instead that the money be donated to humanitarian and peace-building projects for youth. AMONG THE many celebrities attending a gala event at the David Citadel Hotel in Jerusalem last week to promote culture and tourism in the capital was composer and singer Kobi Oz. After the festivities he joined other celebrities in touring the city and took advantage of his visit to the Western Wall to say a prayer. Among the other celebs in attendance were Sarit Vinai Elad, Pnina Rosenblum, Eyal Peled, Shlomi Seranga, Gilad Adin, Ilana Avital, Oren Nahari, Zvika Pik, Sophie Tzadka, Nancy Brandes and Pnina Rosenblum. THE REPORT that Hamas is planning to build a Hollywood-style media city in Gaza, comes at a time when Jewish entrepreneurs in Europe and the US are trying to create something akin to a Jewish CNN. There has also been Israeli interest in such a project. Colorful business mogul and former MK Shmuel Flatto Sharon, who often appears on television and radio as a jovial panelist or interviewee, has been talking about it for some time and at one stage claimed to have American investors who were prepared to join in such a venture. Meanwhile, Bloomberg News is planning to fill the void left in Israel by CNN (which has been dropped by HOT cable), and is in the process of developing a new format. Bloomberg News is very excited about it and says that full details will be made public in the near future.
