The Doctor Who Companion You Likely Didn't Know Starred On Law & Order: UK

In Seasons 3 and 4 of the rebooted version of "Doctor Who," which aired between 2007 and 2008, actor Freema Agyeman portrays a companion to the tenth Doctor (David Tennant) named Martha Jones. In addition to the mainline "Doctor Who" series, she also appears in the same role for a string of episodes of the spinoff "Torchwood." Outside of her work in the BBC's iconic sci-fi franchise, Agyeman's acting career includes a stint as one of the leads of "Law & Order: UK" in its first few years on the air (via IMDb).

Agyeman portrays a prosecutor in the employment of the Crown Prosecution Service named Alesha Phillips on the British crime show. "Law & Order: UK" ran for five seasons in total, though Agyeman's tenure lasted only for Seasons 1 through 3, which aired between 2009 and 2011.

Since then, she's effectively moved her career overseas, co-starring in the Wachowski sisters' Netflix show "Sense8," appearing in Lana Wachowski's "The Matrix Resurrections," and even comprising a part of the main cast of medical drama "New Amsterdam" for more than 70 episodes and counting. Before all of that, though, Agyeman followed up "Doctor Who" by starring in "Law & Order: UK," perhaps paving the way for some of the leading roles later on in her career.
