Although she’s widely known now for being Tom Cruise’s wife, actress Katie Holmes has taken on the challenge of playing another famous significant other.

These pictures of Holmes as former First Lady Jackie Kennedy were taken from the set of The Kennedys, the History Channel’s eight-hour event about the historical family in the years before President John F. Kennedy’s assassination.

The miniseries, which also stars Greg Kinner as JFK and Tom Wilkinson as Joe Kennedy Sr., is scheduled to air sometime in 2011.
