Kristen Bell had "jitters" on the first day of shooting the Veronica Mars movie.

The 33-year-old actress admitted she was nervous about reprising her role as the titular character in the big screen adaptation of the now defunct TV series. Speaking at the San Diego Comic-Con panel for the movie, she said, "It was a lot of excitement and a lot of unknown jitters."

Kristen also revealed her co-star Jason Dohring, who plays her love interest Logan Echolls, was equally nervous: "We kept staring at each other, like 'are we really here? Is this the Twilight Zone?"

Meanwhile, Enrico Colantoni insisted he found it easy to step back into the role of Keith Mars - Veronica's father - because he has a close relationship with Kristen, who recently gave birth to her first child with fiance Dax Shepard. "Kristen and I hang out at hockey games together. It's easy to look at her and have this paternal thing for her. Now, she's a mama. We have more to talk about," he said.
