The 28-year-old actress got so inspired by Helen Hunt's role that she began to dress like her character, reported E!Online.
"I didn't realise you had to be smart. About the time Twister came out with Helen Hunt-my idol-I would dress up in these little khaki shorts and go outside and try to figure out what was happening in the clouds," Seyfried said.
"I had this big weather binder. I was obsessed with the weather," she added.
