Doctor Who star David Tennant is to star in a TV movie about Albert Einstein, writes Jonathan Donald.

Tennant will perform alongside Andy Serkis, who played Gollum in The Lord Of The Rings, in the production titled Einstein And Eddington.

With Serkis as Einstein, it charts the creation of his theory of relativity, one of the most important science breakthroughs of the 20th century.
