Aussie actress EMMA BOOTH is reconsidering plans to become a movie star after seeing what co-star Sienna Miller has to put up on film sets. Booth plays feminist icon Germaine Greer in Hippie Hippie Shake and admits the time she spent with Miller gave her a glimpse of the dark side of fame. She says, "I had a ball getting to know her (Miller) but it's all a bit insane. I was dumbfounded by how the paparazzi chase her. "It was full on and I thought, `Oh dear, is this what's in store for me?'"
