American royalty: Katie Holmes and Greg Kinnear filmed The Kennedys in Ontario, Canada todayThey were hailed as American royalty, so Katie Holmes and Greg Kinnear have rather a tough job on their hands capturing the magic of The Kennedys.
But if the latest on set sneak peek is any indication, they may well be up to the challenge.
Thanks to impeccable hair, make-up and costuming, the pair looked just like the famous couple as they shot scenes for the new 8-hour TV mini-series in Ontario, Canada today.
Katie, 31, who has been filming for the last few weeks, this time wore a purple swing coat while portraying the iconic First Lady Jackie Kennedy while during her pregnancy.
Greg Kinnear, 47, who is best known for his roles in Little Miss Sunshine and As Good as it Gets, wore a sharp suit and shades for his role as JFK.
At one point he was seen throwing an American football and proved to be a rather good catch.
