Legally Blonde Reese Witherspoon star told Showbizspy that it was a "nightmare" to have to wear leg wear while riding a horse for the new movie, which will be released next month.
"I trained to ride an elephant for about three months before filming but I was always wearing jeans," she told the website.
"So when I showed up on set and I actually had to get up there in tights
I was like 'Ouch!' My legs felt like they were getting stabbed by little needles."
She went on to speak about her experiences working with Twilight star Robert Pattinson for the movie saying he is the "nicest guy".
Water for Elephants concerns a young man who joins a circus in Depression-era America, and falls in love with Witherspoon's equestrian performer Marlena.
