Fox’s “The X-Files” follow-up has found some new recruits to seek the truth that’s out there.

Lauren Ambrose (“Six Feet Under”) and Robbie Amell (“The Flash”) will appear in one episode of the upcoming six-episode event series. Character details were scarce and simply described her Agent Einstein as “sharp” and “confident” and his Agent Miller as “smart” and “smooth.” Despite the actors’ likenesses to “X-Files” stars Gillian Anderson and David Duchovny — particularly considering Ambrose’s hair color — sources say this will not be a flashback episode, and it will be set in the present day.

Both Duchovny and Anderson are set to return to their iconic roles as Fox Mulder and Dana Scully. Mitch Pileggi is also back as FBI official Walter Skinner, along with William B. Davis as Mulder and Scully’s frequent foil, the Smoking Man. Guest stars include Joel McHale, Annet Mahendru, Rhys Darby and Kumail Nanjiani.

The six-episode series premieres on Jan. 24 on Fox following the NFC championship game. It is being spearheaded by executive producer Chris Carter, who also created the original series.

Amell is repped by WME, Protégé Entertainment, Coast to Coast, and Felker, Toczek, Suddleson LLP. Ambrose is repped by UTA, Perri Kipperman, and Sloane, Offer, Weber, & Dern.
