Michael Caine, at 76 years old, is in the midst of a career renaissance that should completely cement his role as one of the most important British actors since the 1960s, and in
Harry Brown he has delivered a classic performance that is evocative of previous roles yet doesn't resort to self-imitation or parody. Next to Laurence Olivier, who he more than held his own with in
Sleuth (1972), Caine could be
the most important British film actor ever. Watching just a few minutes of Caine at his prime in the late 1960s explains everything that his current disciples, especially Jude Law and Ewen McGregor, have been trying (and failing) to do ever since. Jude Law hasn't even been subtle about following Michael Caine's career path and has stared in two (and counting) Caine remakes.
Since hitting British film like a shotgun blast in the mid-60s, Caine has, to name just a very few, played one of the cruelest protagonists in film history in
Get Carter (1971), became one of the suavest of ladies men in
Alfie (1966) and effortlessly became a cloistered intellectual in
Hannah and Her Sisters (1986). The reason why Michael Caine has been able to cover this range lies in his unique ability to convey a blend of tough-guy grit and intelligent cool; he's like Sean Connery but with a greater range of emotion (a.k.a. the ability to act). Much of it lies in Caine's voice. He has a strong cockney accent, which is instantly recognizable and can stop a train in its tracks when his anger gets up to full speed. But Caine has never used his distinctive voice as an acting crutch (like, say, Al "Let's Yell Every Fifth Line" Pacino over the past fifteen years) instead, he takes full advantage of silence, and some of his most powerful lines are whispered or delivered extremely slowly.
Harry Brown, his first truly starring role since the underrated
The Statement (2003), allows Caine to revel in anger, and also gives him some of the quietest and most poignant scenes of his career. The film is carried by Caine's performance, but it's also a complicated story of revenge and justice, that poses important questions while not preaching to the audience.
