Tom Everett Scott had never been to Europe, stating: "I hadn't left the country. So it was a really big, brand new experience for me, and I got to work with all these great special effects people and we got to climb all over the Eiffel Tower at night. They would shut it down from midnight to 6 a.m. for our production. I don't know how many people get the opportunity to do that but that was a real thrill.

It is definitely a challenge."
