Although Liam Neeson has apparently dropped out of playing President Abraham Lincoln in a long-awaited biopic because he says the production it's past its sell-by date' - that hasn't stopped him considering a role as President Lyndon B. Johnson instead.

The Schindler's List star, 58, was initially set to renew his Oscar-winning partnership with Steven Spielberg for a movie about the life of the assassinated American leader.

But the project, which Spielberg first mentioned to Neeson in 2005, has taken so long to prepare that the Irish actor has now dropped out because he says he is too old for the role.

Neeson still has the chance to play a former leader of the free world, though - he's accepted a role as U.S. President Johnson in a biopic of murdered civil rights leader Martin Luther King.

Neeson told the press this week: 'I'm not actually playing Lincoln now. I was attached to it for a while, but it's now... I'm past my sell-by date. But I am going to play L.B. Johnson in a movie about Martin Luther King.
