For the second season, star Keri Russell cut her long hair short, and the network moved the show to Sunday nights. Ratings declined. The network blamed it on Russell's hair, not the move to Sundays, and required the rest of the cast not to cut their hair. On both sets of DVDs recently released by the WB, it is mentioned numerous times that Felicity cutting her hair was written into the script by Abrams and Reeves. Keri Russell did not do it on her own.
In season one, episode 5 (Spooked), Felicity sees Ben kissing a girl in a pink Power Ranger costume at the Halloween party. Amy Jo Johnson (Julie) previously played the pink Power Ranger in the Power Ranger series and movies.
In one episode, Noel tells Felicity that he's working on his website, www.noelcrane.com. This was an actual website that included a dorm calendar, dorm party photos, samples from Noel's portfolio, and other details related to Noel's life. The site was updated a few times. The site's ownership has since changed hands and the content has been revised. However, it still looks like Noel's life. The computer script that "runs" at the beginning is a set of instructions for how to be Noel.
J.J. Abrams gave a few nods to 'Star Wars' (in the first season episode 'Spooked' and the one when Noel tells Felicity he's going to Berlin). He later went on to direct the newest 'Star Wars' franchise
