Big-screen charisma looks like it runs in the family. According to director John Carl Buechler, Lindsay Lohan's little sis, Ali, may land a lead role in a big-budget remake of his 1986 camp classic, Troll. Ali auditioned last week and the director enthused, "She was great. The camera loves her. She's a really good actress... I am personally going to fight for her." It's a $25 million remake; the original version featured Sonny Bono and was the film debut of Julia Louis-Dreyfus.
