Hollywood blockbusters about Abraham Lincoln to clash

Robert Redford and Steven Spielberg are pushing ahead with separate films about Abraham Lincoln, despite the prospect of the biopics reaching cinemas at similar times.

Spielberg has said he would continue with his long-planned film about the US president who abolished slavery, after it emerged that Redford was planning a rival project that could be finished first.

The director told Variety magazine that he would not pull the plug on the film, which is set to star Liam Neeson.
