Tom and Katie's 'Kennedy' Date Night

Etertainment Tonight

Tom Cruise and Katie Holmes stepped out in L.A. on Monday night for the premiere of Katie's new miniseries, "The Kennedys."

Katie plays beloved First Lady Jackie Kennedy in the ReelzChannel miniseries, and she said taking on such a lauded historical figure was a tall order: "As exciting as it was, it was daunting because she was loved by so many. You walk into a situation trying your best, but everyone has their idea of who she was and so you're never going to please everyone, so once I got kind of past that then I felt free to create this character."

She said that donning the wardrobe of Jackie's iconic style every day was "really a lot of fun" and said that between wardrobe, hair and makeup, "Once you walked out of the trailer, you felt different, because you had been transformed."

Greg Kinnear, who co-stars as former President John F. Kennedy, also stepped out for the premiere of the miniseries, which will debut April 3 on ReelzChannel.

The cable channel picked up the show after it was announced earlier this year that the History Channel had dropped the show. An A&E rep explained to "ET," "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. We recognize historical fiction is an important medium for storytelling and commend all the hard work and passion that has gone into the making of the series, but ultimately deem this as the right programming decision for our network."
