The screenplay is contrived at times and weakens slightly but the outside location shooting particularly early in the film is spot on. There is a strong British character actor support in Sylvia Syms, Malcolm McDowell, Ken Stott, et al.
The casting of the two leads is excellent and they work well off each other to do justice to the legendary literary partnership. Irene Handl nips in and steals a couple of scenes.
The quality cast are not really challenged by the screenplay. Hoffman looks like Hoffman and Hurt looks like Hurt but Minnie Driver doesn't look like Minnie Driver and maybe, therefore, she has the most challenging role – which she does very well.
