TV period dramas aren’t supposed to be this dramatic.

The Kennedys, the pricey mini-series shot in Toronto by Muse Entertainment and Asylum Entertainment, will not be aired by A&E Television Networks’ History channel stateside, after all.

“Although we regret this does not fit into the History Channel’s plans, we are confident that television viewers in the United States will join viewers from around the world in having an opportunity to watch this series in the near future,” the co-producers said in a statement Friday.

Montreal-based Muse and Asylum are reportedly shopping the $25 million mini-series about the American political family to Showtime and other possible U.S. cable broadcasters.

“Upon completion of the production of The Kennedys, History has decided not to air the 8-part miniseries on the network,” A&E Television Networks, parent of History, said in a statement.

The Kennedys was History’s first move into scripted TV fare.

“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,” the A&E Television Networks statement added.

The mini-series was developed by 24 co-creator/executive producer Joel Surnow and stars Greg Kinnear and Katie Holmes.

Shaw Media’s History Television is set to air the eight-part series from March 6, and a host of other international broadcasters are also to air the project.

The Kennedys portrays the fabled Kennedy clan from the ascent of father Joseph Kennedy to Bobby Kennedy’s assassination in 1968, with the intervening presidency of John F. Kennedy as a dramatic lynch-pin.

The telepic used Cinespace Film Studios’ White House standing sets in Kleinburg, Ontario.
