Season 14, Episode 5 (“Frame by Frame”) focuses not only on a case in the present, but on an unsolved case from 13 years ago that the team was working on until it was taken away by Conrad Ecklie (Marc Vann). became. Throughout the episode there are flashbacks to the first murder and obviously to Sara Sidle (Jorja Fox), Catherine Willows (Marg Helgenberger) and the rest of the team. Fox was very nervous about the flashback scenes, telling The Killing Times, “It’s very, very, very hard, I think, to make us all look 14 years younger for a whole variety of reasons, but it’s certainly going to be fun, to try.”
Since “CSI” didn’t have the budget to use the de-aging technology that is so successful in films, they resorted to other tricks, such as black-and-white shots with soft lights. Fans loved the nostalgia in this episode, especially the return of the character of Catherine since Helgenberger left CSI in Season 12.
