SIFF Cinema wraps up its mini-festival of Hitchcock with two more films you can see 20 times a year on Turner Classic Movies but that you really should see on the big screen. First is 1935's The 39 Steps, the international-espionage-and-errant-murder-accusation roller coaster currently being re-created at Seattle Repertory Theatre. Then comes 1943's Shadow of a Doubt, a slow-boiling stunner featuring a family torn apart by lies and betrayal and an impossibly handsome Joseph Cotten. (SIFF Cinema, 321 Mercer St, 633-7151. 7:30 pm [39 Steps], 9:15 pm [Shadow], $10 for both.)
