There are mysteries — plenty of them, piling enigma on top of inscrutability — but no secrets.

Hands clasped and knees spread wide, the actor — who has become an avatar of inscrutability during his half-century screen and stage career — seems to be trying to shrink himself down to life-size.

But with a script that barely dares to venture into the realms of the unknown, it’s nice to have an actor willing to bump up against some inscrutability.
