By far the best film I have seen in years is the 2014 British film Mr. Turner. Character actor Timothy Spall is spectacular in the title role of British painter J.M.W. Turner (1775-1851).
Turner was, in many ways, a revolutionary artist. Of course he was an eccentric and an irascible but lovable character much like Beethoven, who was a contemporary.
Though awards mean little to me I should point out that the film was nominated for four Academy Awards (best cinematography, best costume design, best original music score and best production design) and Spall won best actor at Cannes, London Film Circle, New York Film Circle and National Film Society of Critics. Which goes to show that occasionally merit is rewarded.
