The Kennedy family saga already seems like a movie thanks to their glamour, good looks, and tragic endings. So it's no surprise they've inspired many films on both the big and small screens. Martin Sheen, who also stared as commander in chief on The West Wing, actually got his presidential-part start in the 1983 miniseries Kennedy — The Presidential Years. More recently, James Marsden and Minka Kelly played Jack and Jackie in Lee Daniels' The Butler, while Ginnifer Goodwin and Rob Lowe gave it a run in this year's Killing Kennedy. Plus, Katie Holmes and Greg Kinnear portrayed the first couple in the 2011 miniseries The Kennedys. After all these years, we clearly can't get enough.
