Case File

, marketed by BBC America as Yaz's Case File, was a series of webcasts released as a tie-in with series 11 of Doctor Who in 2018.

They profiled various monsters and alien races featured on the series, providing information about the villain featured in the episode, as well as an overall episode summary.

As the BBC America name implied, they were a mini-recap of the episodes but from Yasmin Khan's perspective. As such, they contained little new information that wasn't already obvious to the viewer of the main Doctor Who episode.

The series was similar in format to Monster Files, seen during the late RTD/early Moffat era. It also shared some commonality with Sarah Jane's Alien Files that was released with The Sarah Jane Adventures for a time — although that series had more content that was not seen in the accompanying episode.

Note
Oddly, two of the main financiers of Series 11 chose to market the same show in slightly different ways. The official Doctor Who website, run by the BBC, called it simply Case Files and made it available globally. By contrast, the BBC America website called it Yaz's Case File, and geo-locked it.
