Robert Pattinson wore period underpants

Robert Pattinson says he wore “period underpants” while shooting his new movie Water for Elephants.

The hunky Twilight star believes it was the attention to the smallest detail on the set of the ’30s drama that made him produce one of his best performances to date.

“Every single thing which built the world was all totally real,” says Robert. “I even had authentic period underpants. They do actually help, as well. I actually wore them every single day. Jacqueline West, the costume designer, was unbelievable. Almost everything was real. It was crazy.”

Rob who is dating his Twilight costar Kristen Stewart recently revealed he believes in love at first sight.

“I think people can fall in love at first sight,” Rob said. “I think pretty much all people who love each other, had some kind of thing at first sight. I mean, there has to be some kind of moment where you, like, feel a different energy around someone.

“Generally, if you don’t notice someone ever, you’re probably not going to fall in love with them.”

The British hunk plays young veterinarian Jacob, who joins the circus, in romantic drama Water for Elephants. Robert loved shooting scenes with Tai the elephant because he didn’t know what was going to happen. Robert has joked Tai was like a method actor, because the animal never dropped out of character.
"The best thing is that it takes away from the mundane parts of the day. If you're doing 20 takes or something, and there's a character who is going to be doing something totally different every time, it's always exciting,” he told MTV News. “It's like working with a full-on method actor who's just improvising."
Robert stars alongside Reese Witherspoon in the film and he recently recalled that during one day on set Tai released the "most incredible fart into Reese's face... like a hurricane. Thunderous”.
The 24-year-old actor liked the spontaneous experience of working with animals and has revealed the huge beast’s cheeky nature often interrupted highly charged scenes featuring Robert and Reese.
"If there's, like, an actual moment you have to get across [emotion], and suddenly there's, like, a trunk in your face," he laughed. “It's incredible. It just makes everything more interesting."
