(CBS) - Comic-Con attendees were treated to a first glimpse of the honeymoon scene from this fall's "The Twilight Saga: Breaking Dawn - Part 1" Thursday.

One of the scenes, previewed at a panel in Hall H with cast members and director Bill Condon, showed Bella and Edward with a case of the jitters as they stand by their big white nuptial bed in Brazil.

Fans cheered and shrieked as Bella steels her courage to join Edward for a romantic skinny dip along the beach.

Their wedding itself is being kept hush-hush, and Stewart says the ceremony was filmed "Secret Service-style."

"The crew was completely inconvenienced," she said, according to People. "There was no cell phone or email. [But] I said thank you so much [to them] because if this [wedding] dress gets on the Internet, I'll die!"

"The Twilight Saga: Breaking Dawn - Part 1" is due in theaters Nov. 18.
