Jim Broadbent as Sir Oliver Lodge and Donald Sumpter as Max Planck lead the scientific establishments in Cambridge and Berlin as they pervert their scientific beliefs to condone mass killing on a scale never before seen. The drama brings over very effectively the transition from the comfortable life of the scientists in pre-war Cambridge and Switzerland to the tragedies of war. Both Tennant and Serkis get right into the skin of their characters - two brilliant actors on top form. Einstein's complicated private life is compounded by his revulsion at fellow scientists' work in developing poison gas. Tennant shakes off the Dr Who expectations in pointing up the problems of a gay pacifist Quaker who tries to prove the new-fangled theories of 'enemy' scientist Einstein a theory especially dangerous because it undermines the ordered view of the universe created by English scientist Isaac Newton.

The twin leads ≫ritish scientist Arthur Eddington (David Tennant) and Einstein (Andy Serkis) lead very different lives but face not only similar scientific opposition and derision but also similar pressures to back their country's efforts to win the First World War. This is a superb drama, combining a well-presented scientific and historical explication of Albert Einstein's theory of relativity alongside a gripping portrait of the moral dilemmas that scientists have to struggle with as they try to reconcile the demands of country and conscience.
