A minor Hollywood sensation has been caused by the suit which Alberto Guglielmi and Maria Strada brother and sister of the late Rudolph Valentino have filed against George Ullman. They charge Ullman with mismanagement of the estate and diverting large sums of money for his own use. Ullman, in the answer he has filed to the charges, says that, far from mismanaging the estate, he found it in a debt-ridden condition and spent years ironing it out. It was Valentino who wrecked his own estate, Ullman claims, for he died leaving debits of over $60,000 into a surplus of $100,000 to be distributed among the heirs. A court hearing will take place at the end of this month, and a decision reached as is whether Ullman shall be permitted to continue as manager and executor of the estate.
