For a master class in the art of observation (and then writing about it), check out John le Carré's latest visit to a film set. Not only does he muse upon the late great Philip Seymour Hoffman, and filmmaking, and fake beards, but one is put in mind of this earlier piece on a similar topic referring to an equally brilliant and equally flawed actor. (You'll need a subscription to read the whole thing.) The two pieces together present interesting bookends to JlC's magnificent career.
A Most Wanted Man was one of the harder JlCs to fathom, so I'm looking forward to the film to see if I figured it out correctly.
