Jason Isaacs did not receive an Oscar nomination for portraying Mr. Darling/Captain Hook in Peter Pan.
Jason Isaacs as fitting to the tradition of the stage production plays both the role of Mr. Darling and Captain Hook. Isaacs seems like someone who ought to have played Captain Hook sometime in his career, but Mr. Darling presents his side shown far less often. Now we are not given too much time with Mr. Darling though Isaacs does manage to make a nice impression in them, in his approach which differs quite strongly from say the Disney version of the character. In that version we have shades of Hook in Mr. Darling before we see Neverland that's not the case for Isaacs. Isaacs plays Mr. Darling as very much a man of Edwardian England, very proper, very meek but with this undeniable earnestness. In his brief moment where we see his frustrations build towards his children, Isaacs actually successfully creates a sympathy, even when being rather humorous, by showing how desperately Mr. Darling wants to impress his employers. Unfortunately the children lead to an embarrassment where Mr. Darling lashes out. Isaacs effectively handles the scene by portraying the frustration as a burst of sudden emotion, that is not purely cruel rather something far more genuine to a man who otherwise loves children.
Isaacs understands the certain pageantry if you will that goes along with the part, which never compromises the needed menace though. He offers both in a properly intimidating though also incredibly entertaining performance. His Hook has the right sense of mischievousness within the more direct villainy. He never allows his Hook to be defined as only the evil pirate, and has so much of the right sort of fun in the role. I have an especially strong affection for portraying the downtrodden, and falsely empathetic Hook who manages to trick Tinkerbell into helping him. Isaacs is properly amusing in his so falsely, yet appropriately earnest delivery of Hook's concern for Peter Pan. Isaacs finds that right balance in his performance in being the villain but doing it in such an enjoyable fashion. This of course also comes heavily into play in Hook's fear of the crocodile who took his Hook. Although this is not given as much focus as the Disney version, Isaacs still is quite funny in portraying the gripping fear in Hook every moment he believes the crocodile is nearby. Isaacs's Hook steals the film with ease, though I will say that is a fairly common occurrence when it comes to Peter Pan. Isaacs is a great Hook though as he balances the part so well to be such almost oddly endearing fiend for the film. Although it is also worth noting his final return as Mr. Darling where Isaacs is actually rather moving in so honestly portraying Mr. Darling's heartfelt apology for his children. His change of heart is entirely earned, since again even before his lashing out Isaacs's reactions were always that of a caring father. Isaacs excels in both roles being a properly sweet Mr. Darling, and a Captain Hook that captures just about all that the great Captain should be.
