The 12 most popular on-screen presidents of all time, ranked

Hopkins may not look like Nixon, but he mastered the 37th president's mannerisms.

Two years later, he played John Quincy Adams in "Amistad."

Sinise won the 1996 Golden Globe for Best Actor in a Miniseries or TV Film for his role as the 33rd president in the HBO film.

Often considered the greatest US president, Abraham Lincoln scores here with the method actor's fascinating embodiment of the Republican's careful maneuvering, compassion, and soaring rhetoric. (Also, really long stories.)

It may not be the most scientifically accurate film, but there's no denying "the voice of God" as President Tom Beck soothing a nation about to be pummeled by a comet.

In a January 2008 issue of TV Guide, Haysbert claimed that his role as President David Palmer was responsible in part for Barack Obama's election.

"As far as the public is concerned, it did open up their minds and their hearts a little bit to the notion that if the right man came along that a black man could be president of the United States," he said.

His costar Kiefer Sutherland denied Haysbert's claim.

Sheen won the Golden Globe for Best Actor in a Drama TV Series in 2001 for his role as Josiah "Jed" Bartlet.

Fonda played The President in the film based on the 1962 novel about a Cold War crisis.

He also played the president in 1979's "Meteor" opposite Natalie Wood and Sean Connery.

Douglas played a widowed president, Andrew Shepherd, who fell in love with a lobbyist (Annette Bening).

"Frost/Nixon" won the 2009 Oscar for Best Picture.

Langella was nominated for multiple awards, including the Academy Award for Best Actor.

He may not have won any awards, but Pullman's portrayal of Thomas Whitmore is probably one of the most recognizable presidential roles. He ranked third in The Credits' poll for all-time popularity.

Sure, Pullman may not be the most realistic president, but he wins our vote for jumping in an aircraft to shoot down some alien scum for the survival of mankind alongside Will Smith.

Before Liam Neeson was "Taken," Harrison Ford took down Gary Oldman and a group of Russian terrorists who kidnapped him and his family as President James Marshall.

Ford received the most votes in The Credits' poll.

We can't even really blame Trump for trying to use the music from the movie in his campaign.

Jon Voight's performance of Franklin D. Roosevelt in "Pearl Harbor."

Danny Glover played Thomas Wilson in "2012."

Tommy "Tiny" Lister as President Lindberg in "The Fifth Element."

And, of course, Jack Nicholson as President James Dale in "Mars Attacks."
