Lucy Lawless will play Isabel Hartley on season 2 of the Marvel series "Agents of S.H.I.E.L.D."

Lucy Lawless has many talents, as any fan of Xena, the Warrior Princess, will tell you. She can throw a chakram, deliver a baby while the hordes are attacking and sing better than the Sirens.She also does a mean Stevie Nicks. Lawless will now get to apply her considerable skills of espionage.

Producers of "Agents of S.H.I.E.L.D." confirmed that Lucy Lawless will play a longtime S.H.I.E.L.D. veteran, Isabel Hartley.

During a Marvel television panel at Comic-Con on Friday, executive producer Maurissa Tancharoen said "She's tough. She may have a knife always by her side."

"Agents of S.H.I.E.L.D" follows a team of highly skilled agents who investigate strange occurrences around the world. Lucy Lawless, who's last starring role came on Showtime's "Spartacus," is no stranger to investigating strange occurrences. After Xena lost her head and left Gabrielle to fend for herself in the mythical ancient Greece, Lawless spent some time heating up "The X-Files."

On Friday at San Diego's Comic-Con, a Marvel TV panel announced that directors Joe and Anthony Russo, who helmed "Captain America: The Winter Soldier," will direct Agents of S.H.I.E.L.D'S second and third episodes which will debut in 2015 on ABC.
