Katie Holmes' hit-challenged career took another blow Friday when the A&E Television Networks dumped its highly-touted The Kennedys miniseries, RadarOnline.com has learned.

Calling the finished product "historical fiction," execs at the cable net pulled the plug on its upcoming airing on The History Channel. With Holmes as Jackie and Greg Kinnear as John Kennedy, the eight-parter had been much anticipated and would have put Holmes back on the map as a legitimate star.

"While the film is produced and acted with highest quality, after reviewing the final product in its totality, we have concluded this dramatic interpretation is not a fit for the History brand," an A&E rep told The Hollywood Reporter.

The project will be seen internationally but that is likely to offer little comfort to Katie who hasn't had a hit film since 2005; before she was Mrs. Tom Cruise.
