Ben Kingsley - who is always great - does some scenery-chewing as Soussan's more experienced boss, but even Kingsley's presence isn't enough to make things work.

Theo James, whose voice is quite engaging and easy on the ears, also narrates 'BFB,' which helps us follow this complicated fictionalized version of Michael Soussan's compelling memoir.

Although the narrative momentum lags in spots, the film takes advantage of strong performances and captures its inherent moral complexity without turning didactic or heavy-handed.
