John Powers

At its core, John le Carre's Tinker, Tailor, Soldier, Spy isn't really about espionage, says critic John Powers. The 1974 novel, adapted for the screen in 1979 by the BBC, is actually about secrets and lies and shifting identities -- which is to say, a metaphor for our own daily lives.

It's been more than 30 years since the rugged film star's death, yet he still looms large in the national psyche. Critic John Powers was surprised to find that the indomitable American fighting man was actually a hard-earned act of self-invention.

Roger Ebert tackles lowbrow and highbrow topics alike in his memoir; critic John Powers says the chronicle is sunny and hopeful — just like Ebert himself.
