2008_08_jerryo.jpgMarta Curro, Jerry Orbach's first wife, is defending her son's recent vitriolic letter to his step-mother, which was leaked to the Post. The letter accuses Orbach's second wife Elaine Cancilla-Orbach of screwing Chris Orbach and his brother out of the $10 million estate left by their father, which they can't dip into until she dies. (The letter also blames Cancilla-Orbach for manipulating Orbach to donate his eyes after his death.) But the 75-year-old Curro, who was married to Orbach for 17 years and remained close with the actor after their divorce, says her son is right to be angry at wife #2: "She's funny looking and she wears polyester pantsuits, and that just makes me laugh. There's nothing funnier to me than stupid people being evil, because they put a tack on your chair and expect it to kill you."
