Watch Katie Holmes starring as Jackie Kennedy in the HISTORY mini-series, The Kennedys.

The 32-year-old actress – mum to four-year-old Suri with husband Tom Cruise – plays the President’s wife opposite Greg Kinnear as JFK.

Katie revealed at the Los Angeles premiere: “I love how strong she was and what a great mum she was. She was very supportive of her husband and she did so much for our country, and she’s had lasting influence.

“So I just started from there and I approached this work knowing what a strong woman she was.”

The Kennedys, which has had a troubled gestation after accusations of inaccuracy, screens on HISTORY in the UK on April 7, and on BBC 2 in May or June.
