Alias actress Jennifer Garner, who stars as a CIA agent in the show, is now fronting a recruitment drive for the US spy agency.
The CIA said garner was not paid for the ad
She agreed to appear in a video for the CIA's website urging potential candidates to sign up.
The website states that Garner's Alias character "embodies the integrity, patriotism and intelligence the CIA looks for in its officers".
Garner, 31, was not paid for her appearance in the advert.
A CIA spokesman said: "She did this out of patriotism."
One the website Garner says the agency needs staff from a diverse range of backgrounds and with different talents.
Garner starred in Daredevil as well as Alias
"Right now, the CIA has important, exciting jobs for US
citizens, especially those with foreign language skills. Today, the collection of foreign intelligence has never been more vital for national security," Garner says.
Agencies such as the CIA have been criticised since the 11 September attacks on America for not having enough staff who could speak Asian or Middle Eastern languages, which may have helped thwart attacks.
As well as her role on Alias, Garner appeared as one of the hosts of last month's Oscars awards ceremony.
She also appeared in the movie version of the comic strip Daredevil, alongside Ben Affleck.
