Rachel McAdams calls it a "privilege" to work with the late Philip Seymour Hoffman.
A Most Wanted Man is one of the last films Philip Seymour Hoffman completed before his tragic death earlier this year, but his legacy and his memory will live on in the hearts and minds of those he worked with, and those he inspired.
Once such person is Hoffman's Most Wanted Man co-star Rachel McAdams, who stopped to talk to ET while walking the red carpet at the New York premiere of the film, screened at the Museum of Modern Art on Tuesday night.

"I just think one of the greatest actors of our time," McAdams said. "It was such privilege to watch him work and get to see that up close."
In A Most Wanted Man, based on a novel by Tinker Tailor Soldier Spy author John le Carre, Hoffman plays German intelligence operative Gunter Bachmann, while McAdams plays human rights lawyer Annabel Richter. Bachmann, working with US intelligence, must set a trap for a group of extremists, and he uses Richter as part of his plan.
"I feel very lucky I got to work with him," McAdams added. "And this is another extraordinary performance by him."
