Martin Landau

I cannot count the number of times I have seen the outstanding 1959 Alfred Hitchcock film North by Northwest, which starred Cary Grant and Eva Marie Saint.  The film never disappoints.

One of its great supporting performances was by the wonderful actor Martin Landau, who played Leonard, the right-hand man to James Mason's Phillip Vandamm.  

Mr. Landau died on Saturday, at age 89.

Another of my favorite performances by Mr. Landau was his supporting role--for which he received an Oscar nomination--in Woody Allen's Crimes and Misdemeanors (1989). 

Mr. Landau's obituary in The Washington Post noted this, about his Crimes and Misdemeanors role:  "Newsweek arts writer Cathleen McGuigan spoke for many critics when she wrote that his 'delicate, tortured performance as a successful man caught in the web of his deceits is a tour de force.'"

Here, lastly, is part of a scene from North by Northwest; the scene includes Cary Grant, James Mason, and Mr. Landau.
