(The Press Association) - Rachel Bilson said she felt a little uncomfortable filming love scenes with Hayden Christensen in sci-fi movie Jumper.
"It's always awkward and hard to film love scenes, it's so unnatural, and it's mechanical," she said.
"Actually Doug [Liman, director] made it very free and we went with it - and a shot of alcohol always helps ease the nerves."
However, Rachel had a blast making the film with co-stars Hayden, Jamie Bell and Samuel L Jackson.
"It was so fantastic, the whole experience," she said. "We all became close friends, but I also respect all of them as actors so I got to learn things from them. I was very fortunate."
The shoot involved Rachel visiting exotic locations including Italy and Egypt.
"Travelling was awesome, we went to so many different places," she said.
"We shot inside the Coliseum in Rome which was pretty fantastic. I was in Egypt and places I never really thought I'd go to. Standing in front of the Sphinx was very surreal. Only in this business I guess."
But there's still a few places the former OC star would like to go.
"You only live once so you should see as much as you can," she said. "I want to go to India and I want to go to Thailand. I travel a lot, it's hard on your body, but the experience is worth it."
