It appears the actual Kennedys are the ones to thank played a role in the cancellation of The Kennedys – a miniseries once destined for the History Channel.

The eight-hour event, featuring Greg Kinnear as President John F. Kennedy, was to have focused on focus on the personal relationships within the famous family. And though Katie Holmes “worked as hard” as she could to portray former First Lady Jackie Kennedy, the project was scrapped from the channel’s schedule.

“Upon completion of the production of The Kennedys, History has decided not to air the 8-part miniseries on the network,” a rep told The Hollywood Reporter. “While the film is produced and acted with the highest quality, after viewing the final product in its totality, we have concluded this dramatic interpretation is not a fit for the History brand.”

According to insiders, real-life members of the Kennedy clan – including Caroline Kennedy and Maria Shriver -- were instrumental in getting the program canned.

There is still hope the series will air on a different channel in the future. In the meantime, The Kennedys is still scheduled for broadcast outside North America.
